Vanillin 99.5% AR Grade Reagent
Cas Number:121-33-5
Formula: C8H8O3
Molar Mass:152.15
EC Number:204-465-2
Physicochemical properties:
White or milky white needle crystals with pleasant vanilla smell. It is sensitive to humidity. Slow oxidation in exposed wet air. Affected by light. 1 g is dissolved in 100 ml of water, 16 ml of 80 ° C hot water, and about 20 ml of glycerin. It is soluble in ethanol, chloroform, diethyl ether, carbon disulfide, glacial acetic acid and pyridine, also soluble in oil and alkali hydroxide solution, the solution is acidic to litmus. The relative density is 1.056.
Usage:
Test protein, azaindole, phloroglucinol, tannic acid, iron ions. Chlorine was measured from benzoic acid. Spices. Organic microanalysis determines the standard for methoxy groups.
Packing:
