3,5-DIIODOSALICYLALDEHYDE CAS 2631-77-8 synthesis; Chemical raw materials; Organic raw material aldehyde;
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..
