The preparation of 3-pyridyl formaldehyde and 6-bromo-5-methyl can be done according to the following ancient methods.
First take an appropriate amount of 5-methyl-3-pyridyl carboxylic acid as the starting material, which is the basis for preparation. Place it in a reactor and slowly add an appropriate amount of halogenating reagent. The halogenating reagent should preferably be a brominating reagent, such as bromine or a compound containing bromine, to promote the introduction of bromine atoms at the 6-position of the pyridine ring. The reaction process needs to be strictly controlled, generally maintained in a moderate temperature range, such as 50-80 degrees Celsius, and it needs to be protected by an inert gas to prevent impurities from invading the reaction. The purpose of this step is to precisely introduce bromine atoms at specific locations to meet the structural requirements of the target product.
After the bromination reaction is completed, the reaction products are finely separated and purified, and the unreacted raw materials and by-products are removed. Commonly used methods, such as column chromatography, utilize the difference in the partition coefficients of different substances between the stationary and mobile phases to achieve the purification of the product, resulting in a purified 6-bromo-5-methyl-3-pyridinecarboxylic acid.
Then, the purified 6-bromo-5-methyl-3-pyridinecarboxylic acid is reduced. Suitable reducing agents can be used, such as lithium aluminum hydride. This reducing agent has strong reducing properties and can reduce carboxyl groups to aldehyde groups. The reaction also needs to be carried out under specific conditions, such as low temperature environment, about 0-10 degrees Celsius, and the reaction system needs to be anhydrous and oxygen-free to ensure the smooth progress of the reaction. After the reduction reaction is completed, the product is carefully separated again by suitable separation means, such as distillation or recrystallization, to obtain high-purity 3-pyridinal formaldehyde and 6-bromo-5-methyl products.
Every step of the reaction needs to be carefully controlled, from the amount of raw materials, the purity of the reagent, to the temperature and time of the reaction, all of which are related to the yield and purity of the product. When operating, it is also necessary to follow the ancient laws and regulations and proceed with caution in order to obtain this product as desired.

I don't know the price range of 3-pyridyl formaldehyde and 6-bromo-5-methyl in the market. However, "Tiangong Kaiwu" is a book on all kinds of process creations, not a book on the price of this product, so it is difficult to answer according to it. If you want to know the market price of this product, you can consult chemical merchants for materials, or check the chemical product trading platform, which may have relevant price information for reference, so that you can get its approximate price range.

3-Pyridyl formaldehyde, 6-bromo-5-methyl, the conditions for its storage are quite critical. It needs to be placed in a cool and dry place, away from the heat source and fire. These substances are delicate and easily disturbed by external factors.
In a cool place, the temperature needs to be maintained at a low state, not too high, to prevent its internal structure from changing, causing its properties to change. A dry environment is also indispensable. If the moisture is too heavy, it is easy to cause deliquescence, or cause chemical reactions to occur without reason, which will damage its original characteristics.
Furthermore, it must be isolated from oxidizing substances. Oxidative substances are highly active, and when they coexist with them, they are prone to violent reactions, or cause explosions, fires and other disasters. And should be placed out of the reach of children to prevent accidents and endanger personal safety.
The storage place should also be kept well ventilated. If the air is not circulated, harmful gases accumulate, or affect the quality of the material, and there is also a risk to the health of the person who takes it. The storage container should also be carefully selected to ensure that it is well sealed to prevent the material from evaporating or contacting with the outside air components, so as to preserve its quality and its properties. In this way, the effect of proper storage can be obtained.
