Phenol 99% AR Grade Reagent
Cas Number:108-95-2
Formula:C6H6O
Molar Mass:94.11
EC Number:203-632-7
Physicochemical properties:
Colorless needle crystal or white frit with special odour. Exposure to the air and exposure to light It will turn to red while exposured to air and light. When it does not contain moisture and cresol, it will solidify at 41 ° C and melt at 43 ° C. General commodities contain impurities that increase the melting point. It can be liquefied by mixing with about 8% of water. 1g of this product is soluble in about 15ml water and 12ml benzene, soluble in ethanol and chloroform.
Usage:
Nitrate and nitrite are measured colorimetrically in a sulfuric acid solution. Indirect determination of potassium. Used to bind excess free halogen. The oxide of the alkaline earth metal is measured. Determination of ammonia, hypochlorite, 1-hydroxy acid. As a solvent for measuring the molecular weight of the refractory compound. Microscopic staining, etc.
Packing:
500g/25kg
