1H-Benzotriazole CP Grade Reagent
Cas Number:95-14-7
Formula:C6H5N3
Molar Mass:119.12
EC Number:202-394-1
Physicochemical properties:
White or light brown needle crystals. Odorless. It oxidizes in the air and gradually turns to red. An explosion can occur when distilled in a vacuum. Soluble in ethanol, benzene, toluene, chloroform and N, N-dimethylformamide, slightly soluble in water. The melting point is 98.5 ° C (100 ° C). The boiling point is 204 ° C (2.00 kPA). The flash point is about 170 °C. The minimum lethal dose (rat, oral) is 500 mg/kg. Irritating.
Usage:
When combined with ammonium hydroxide and ethylenediaminetetraacetic acid, silver, copper, and zinc can be selectively measured. Photo anti-fogging agent. Photoinhibitor. Organic Synthesis.
Packing:
500g/25kg
