4-Nitrophenyl chloroformate CAS 7693-46-1 liquid. The boiling point is 159-162 °C19 mm Hg(lit.), the relative density is 1.5719 (rough estimate), the refractive index is 1.6000 (estimate), and the flash point is >110°C.
Diethyl cyanomethylphosphonate CAS 2537-48-6 is a colorless transparent liquid with a density of 1.095, a boiling point of 101-102°C and a refractive index of 1.4312-1.4332. It is used for the preparation of 2-aminoquinoline. 2-Aminoquinoline can be used to prevent or treat depression, anxiety disorders, schizophrenia Chemicalbook disorder, panic disorder, agoraphobia, social phobia, obsessive-compulsive disorder, post-traumatic stress disorder, pain, memory disorders, dementia, eating behavior disorder , sexual dysfunction, sleep disturbances, substance abuse, movement disorders such as Parkinson's disease, psychiatric disorders or gastrointestinal disorders.
D-Tartaric acid CAS 147-71-7 exists in three stereoisomers: tartaric acid, levo-tartaric acid and meso-tartaric acid. The optically active phases of a mixture of equal amounts of dextro- and levorotatory bodies cancel each other out, which is called racemic tartaric acid. Meso does not exist in nature and can be synthesized chemically. All kinds of tartaric acid are colorless crystals that are easily soluble in water..
L(+)-Tartaric acid CAS 87-69-4 is colorless translucent crystal or white fine to coarse crystalline powder with sour taste.
5-Chlorovaleryl chloride CAS 1575-61-7 is an important synthetic intermediate of pyrazole herbicides. 5-Chloropentanoyl chloride is used as the raw material of 1,1,7-trichloro-1-hepten-3-one, and then the third-generation pyrazole herbicides can be synthesized. Pyrazole herbicides have the characteristics of ultra-efficient chemical activity, high selectivity, extremely low mammalian toxicity and good environmental characteristics, etc., and have become the hot spot of herbicide research and development in the world in recent years. As the demand for high-efficiency herbicides continues to expand, so does the demand for 5-chlorovaleryl chloride as an intermediate.
Diphenylmethane CAS 101-81-5 is a colorless needle-like crystal with an orange fragrance. Insoluble in water, soluble in ethanol, ether, chloroform, benzene and cyclohexane.
