121102104
Formamide 99% AR Grade Reagent
Cas Number:75-12-7
Formula:CH3NO
Molar Mass:45.04
EC Number:200-842-0
Physicochemical properties:
Colorless micro-viscous liquid with dorless or slightly ammoniatic. It is hygroscopic. In the presence of moisture, it can be hydrolyzed to ammonia and formic acid. Partially decomposed into carbon monoxide and ammonia at 180 ° C under one atmosphere. It is miscible with water, methanol, ethanol, acetone, acetic acid, dioxane, ethylene glycol and phenol. It is very slightly soluble in ether and benzene. It can dissolve casein, glucose, corn bran, tannin, starch, lignin, polyethylene.
Usage:
Ionizing solvent. Paper chromatography developer. A softener for animal glue. Softener for the fiber industry. Production of formate and hydrocyanic acid.
Packing:
500ml/25L/200L
