Properties and stability
Avoid contact with moist air. Avoid contact with strong oxidants and water.
Highly toxic and highly irritating to mucous membranes, skin and tissues, so avoid oral administration. Sudden mutation of microsomesTest: Typhimurium 1×10-6mol/plate. Leakage should be prevented during production, and operators should wear protective equipment.
Storage method
Stored in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The storage temperature should not exceed 30℃. The packaging is sealed. They should be stored separately from oxidants, food chemicals, etc., and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills.
Sealed and packaged in glass bottles and wooden boxes. Store and transport according to regulations for flammable and toxic substances. Handle it carefully to prevent damage.
Synthesis method
Originated from acid chloride of 3,5-dinitrobenzoic acid. Slowly add thionyl chloride to 3,5-dinitrobenzoic acid, heat and reflux for 4-5 hours, and recover the thionyl chloride under reduced pressure. The residue is recrystallized with carbon tetrachloride to obtain the finished product.
Purpose
It is used as a reagent for the determination of various alcohols, organic synthesis, pharmaceutical industry, and disinfection preservatives and reagents.
