L-Phenylalanine benzyl ester hydrochloride CAS 2462-32-0 can be used in biochemical reagents and pharmaceutical intermediates.
5-Fluoro-2-nitroaniline CAS 2369-11-1 is Anilines, Aromatic Amines and Nitro Compounds
trans-Cinnamic acid CAS 140-10-3 rheumatic drug ketoprofen, etc.), curing accelerators.
2-Methoxy-5-nitropyridine CAS 5446-92-4 is obtained by etherification of 2-chloro-5-nitropyridine. Sodium methoxide was added dropwise to the mixture of 2-chloro-5-nitropyridine and methanol under stirring, and crystals were precipitated in crushed ice after adding sulfur for 1 h. Filter, dry, and recrystallize with methanol to obtain the finished product. The yield was 92%.
N-Iodosuccinimide CAS 516-12-1 is a white needle-like crystal, decomposes in contact with water, soluble in water, methanol, dioxane, and insoluble in carbon tetrachloride. The silver salt of succinimide can be obtained by first reacting the aqueous solution of succinimide with silver oxide, and then reacting with iodine and the like. N-Iodosuccinimide can be used as a reagent to iodide aldehydes and ketones.
4-Chlorobenzoic acid CAS 74-11-3 is white powdery solid, m.p.239~241℃, soluble in methanol, absolute ethanol and ether, very slightly soluble in water, toluene and 95% ethanol.
