Second, the price of raw materials also affects. If the price of raw materials required for the preparation of this product rises, the price of the finished product will also rise; if the price of raw materials falls, the price of the finished product may decrease. Third, the difficulty of preparation and the simplicity of the process are also related to the price. If the preparation requires exquisite craftsmanship and harsh conditions, the cost will be high and the price will be high; if the preparation is easier, the cost will be reduced and the price will be low.
Furthermore, the prices set by different merchants are also different. Large merchants have slightly lower prices due to scale effects, cost or controllability; small merchants may have slightly higher prices due to factors such as operating costs. And different sales regions have different prices. In places with convenient transportation and fierce market competition, the price may be more competitive; in remote places, due to increased costs such as transportation, the price may be higher. < Br >
Therefore, in order to know the exact market price of this 3-bromo-2-hydroxypyridine with 99% purity, it is necessary to consult the chemical raw material supplier in detail and compare its quotation to obtain a more accurate figure.
3-Bromo-2-Hydroxypyridine 99% of the production process complicated?
3-Bromo-2-hydroxypyridine, with a purity of 99%, the production process is simple and simple, depending on various factors.
To prepare this compound, the common method, or the pyridine derivative through bromination and hydroxylation sequence. If pyridine is used as the initial material, to introduce bromine atoms at 3 positions and hydroxyl groups at 2 positions, the bromination step requires the selection of appropriate brominating reagents, such as bromine, N-bromosuccinimide, etc., and the temperature of the reaction, the time and the ratio of the agent must be controlled to ensure that the bromine atoms fall precisely at 3 positions. This is not an easy task, and the product is impure due to a slight difference.
As for the hydroxylation process, there are also various paths to be found. The method of nucleophilic substitution can be used to introduce the hydroxyl group into the two position with a suitable hydroxylation reagent under specific reaction conditions. However, the fine regulation of reaction conditions involved, such as the strength of the base and the choice of solvent, all have a great impact on the process of the reaction and the yield and purity of the product.
In addition, the purity of the raw materials and the sophistication of the reaction equipment also affect the difficulty of the production process. If the raw materials are impure, impurities may interfere with the reaction, which makes the reaction more complicated. And sophisticated equipment can accurately control the temperature and pressure to ensure that the reaction proceeds as expected. If the equipment is simple, it is difficult to achieve this accuracy.
Overall, the production process of 3-bromo-2-hydroxypyridine with 99% purity is not the simplest way, and it is necessary to carefully control each reaction link and consider many factors to obtain high-purity products.
3-Bromo-2-Hydroxypyridine 99% of the quality of how to test
To test the quality of 3-bromo-2-hydroxypyridine (99% purity), you can follow the following methods.
First, the melting point determination method. This substance should have a specific melting point range. In the context of "Tiangong Kaiwu", although there is no accurate melting point meter today, it can be simulated with a simple device. Prepare a capillary tube, take an appropriate amount of the substance, and fix it near the heating device. Heat with a slow fire and pay close attention to changes in the substance. If its purity reaches the standard, it will melt rapidly in a relatively narrow temperature range. If it contains more impurities, the melting point will be reduced and the melting range will be widened.
Second, chromatographic analysis. In analogy to the ancient method of separation of substances, today's chromatography is such as thin-layer chromatography (TLC) or high-performance liquid chromatography (HPLC). During TLC, choose a suitable silica gel plate, point the sample solution, and place it in a closed container containing a specific development agent. Due to the different distribution coefficients of different substances between silica gel and development agent, separation is achieved. If the substance is pure, a single spot will appear on the plate. HPLC is more accurate and can determine its purity according to retention time and peak area.
Third, elemental analysis method. The content of carbon, hydrogen, nitrogen, bromine and other elements in the substance can be measured. Calculate the theoretical element ratio according to its chemical formula, and then compare it with the measured value. If the measured values are in good agreement with the theoretical values, the purity is good; if the deviation is large, it contains more impurities.
Fourth, spectral analysis method. Such as infrared spectroscopy (IR), different functional groups have characteristic absorption peaks in the infrared region. 3-Bromo-2-hydroxypyridine of hydroxyl, pyridine ring, bromine, etc. have corresponding absorption peaks. If the spectrogram is consistent with the standard spectrum and there are no additional heterogeneous peaks, it can be proved that its purity is high.
What are the storage conditions for 3-Bromo-2-Hydroxypyridine 99%?
3-Bromo-2-hydroxypyridine, with a content of 99%, its storage conditions are quite critical. This compound should be placed in a cool, dry and well-ventilated place. In a cool environment, it can avoid changes in its properties caused by high temperature. Due to high temperature or the acceleration of its chemical reaction, its purity is damaged. The need for drying is to prevent it from getting damp. Wet gas, or react with the substance, causes it to deteriorate. Good ventilation can disperse harmful gases that may be volatile in time, maintain its quality and protect environmental safety.
Furthermore, when storing, it needs to be separated from oxidants, acids, bases and other substances. The oxidizing agent has strong oxidizing properties, or oxidizes with 3-bromo-2-hydroxypyridine; acid-base contact with it may also initiate chemical reactions and change its chemical structure and properties.
Packaging should also be tight. High-quality packaging can effectively block external factors such as moisture, air, etc. The choice of packaging materials should be adapted to the characteristics of the compound to prevent leakage and damage.
In addition, the storage area should be equipped with corresponding fire and leakage emergency treatment equipment. In case of an accident, it can respond quickly and reduce damage hazards. And it should be managed by a special person to regularly check its storage status to ensure all compliance, to ensure that 3-bromo-2-hydroxypyridine is in good storage conditions, and to maintain its high purity quality.
