5-Bromo-2-Pyridinecarboxylic Acid Ethyl Ester

Ethyl 5-bromo-2-pyridinecarboxylate, which is a kind of organic compound. Its shape is colorless to pale yellow liquid, or it is a crystalline solid, depending on the ambient temperature.
It has a specific melting point and boiling point. The melting point is about [specific value], and the boiling point is around [specific value]. This compound exhibits good solubility in organic solvents such as ethanol, ether, dichloromethane, etc., but its solubility in water is quite low. This is determined by the ratio and characteristics of polar and non-polar parts in its molecular structure.
In terms of chemical properties, it is extremely active. The bromine atom in the molecule, due to the large electronegativity of bromine element, makes the carbon-bromine bond polar, so it is prone to nucleophilic substitution reactions. Under basic conditions, such as co-heating with alcohol solutions of sodium hydroxide and potassium hydroxide, bromine atoms can be replaced by hydroxyl, alkoxy and other nucleophiles to form corresponding derivatives.
In addition, its pyridine ring also has unique chemical activity. The nitrogen atom in the pyridine ring has lone pairs of electrons, which makes the pyridine ring weakly basic and can react with acids to form pyridine salts. At the same time, the pyridine ring can undergo electrophilic substitution reactions under certain conditions, but the reactivity is slightly lower than that of the benzene ring, and the substitution positions are mostly preferentially occurring on the carbon atom at the interposition of the nitrogen atom of the pyridine ring.
Furthermore, the ester group in the molecule is also an active reaction check point. Under acidic or alkaline conditions, hydrolysis can occur. When acidic hydrolysis, 5-bromo-2-pyridinecarboxylic acid and ethanol are formed; when alkaline hydrolysis, 5-bromo-2-pyridinecarboxylate and ethanol are formed. After subsequent acidification treatment, 5-bromo-2-pyridinecarboxylic acid can also be obtained.
This compound is widely used in the field of organic synthesis and is often used as a key intermediate to prepare various drugs, pesticides and functional materials containing pyridine structures. It is of great significance in many fields such as medicinal chemistry and materials science.

A common synthesis method of ethyl 5-bromo-2-pyridinecarboxylate can be prepared by esterification reaction of 5-bromo-2-pyridinecarboxylic acid and ethanol under acid catalysis. This reaction is usually carried out under the condition of heating and refluxing. Commonly used acid catalysts such as concentrated sulfuric acid and p-toluenesulfonic acid. Although concentrated sulfuric acid has high catalytic activity, it has many side reactions; p-toluenesulfonic acid is relatively mild and has few side reactions.
5-bromo-2-chloropyridine can also be used to react with sodium ethyl alcohol to generate 5-bromo-2-pyridineethanolate through nucleophilic sub This method needs to pay attention to the control of reaction conditions. Due to the high activity of halogenated pyridine, the reaction is easy to overdo or produce impurities.
In addition, using 2-ethyl pyridinecarboxylate as raw material, 5-bromo-2-ethyl pyridinecarboxylate is prepared by introducing bromine atoms through bromination reaction.

The market price of ethyl 5-bromo-2-pyridinecarboxylate is difficult to summarize. This is because the market price is often influenced by many factors, such as the state of supply and demand, manufacturing costs, quality, market competition, and even macroeconomic conditions.
Let's talk about supply and demand first. If the market faces strong demand for ethyl 5-bromo-2-pyridinecarboxylate, and the supply is relatively scarce, its price will rise; conversely, if demand is weak and excess supply, the price will be depressed. It is the change of market supply and demand that is the key to price fluctuations.
Manufacturing costs are also a major factor. The price of raw materials, the simplicity of the production process, and the amount of energy consumption are all related to the cost. High raw material prices, or complex processes lead to a large increase in costs, and product prices will also rise.
The impact of quality should not be underestimated. High-quality 5-bromo-2-pyridinecarboxylate ethyl ester, due to the need for more precise production control and testing, the price is often higher than that of ordinary quality.
Furthermore, the market competition situation has a deep impact. If there are many congeneric products in the market, and each merchant is competing for a share, it may use the price as a weapon to reduce the price and promote the price, so that the price will be lower; conversely, if the market monopoly is strong, the price may be more manipulative.
Macroeconomic conditions also influence prices. The economy is prosperous, the market is full of vitality, and demand is rising, which may help prices increase; in the economic downturn, the spending power of enterprises and consumers is reduced, and prices may also be depressed.
Therefore, in order to determine the market price of 5-bromo-2-pyridinecarboxylate, it is necessary to observe the market dynamics in real time and comprehensively consider the above factors to obtain a relatively accurate price.

Ethyl 5-bromo-2-pyridinecarboxylate is an important compound in organic chemistry. During storage and transportation, many matters need to be paid careful attention.
Temperature and humidity of the first storage environment. This compound should be stored in a cool, dry place, away from heat and fire sources. High temperature can easily cause its chemical properties to change, causing decomposition or other adverse reactions; excessive humidity, or make it damp, affecting purity and quality. For example, if placed in a hot flush place, it may cause reactions such as hydrolysis, which will damage its structure and performance.
The second is the choice of storage containers. Containers with good sealing properties, such as glass bottles or specific plastic bottles, should be used to prevent contact with air. Because of its reaction with oxygen, carbon dioxide and other components in the air. Like some compounds containing active groups, which are in contact with the air for a long time and are easily oxidized, ethyl 5-bromo-2-pyridinecarboxylate may also have this risk.
Furthermore, its stability must be ensured during transportation. Avoid violent vibration and collision to prevent compound leakage due to package damage. If transported by vehicle, the cabin should maintain suitable temperature and humidity, and should not be mixed with oxidants, acids, alkalis and other substances. Due to 5-bromo-2-pyridinecarboxylate or dangerous chemical reactions with these substances, such as meeting with strong acids and alkalis, or causing hydrolysis of ester groups, endangering transportation safety and product quality.
In conclusion, the storage and transportation of ethyl 5-bromo-2-pyridinecarboxylate requires all-round consideration of factors such as temperature and humidity, containers, and transportation conditions, and careful attention to ensure its quality and safety.
