Product Usage
White to yellow-white fine crystal, or crystalline powder, slightly rice sugar like peculiar odor, bitter taste, easy moisture absorption, dry products in the air quickly absorb about 4% of the water. 1g of this product is soluble in 1mL of water and 100mL of ethanol, soluble in glycerol but insoluble in ether and benzene. Melting point about 248ºC (decomposition). Under acidic conditions, the heat is more stable, when the pH is equal to 3 Chemicalbook, even if the high pressure cooking to 140ºC for 1h, the damage is little. However, it is easy to decompose in neutral and alkaline solutions, and if it is boiled at a pH greater than 7, most or all of it is destroyed, and even stored at room temperature can be gradually destroyed. It can be inactivated by oxidation or reduction. Sensitive to light. Exposure to the air is easy to absorb moisture, and dry products quickly absorb 4% of moisture in the air.
White acicular crystal or crystalline powder, with a faint rice-chaff odor and bitter taste. Melting point 248 ~ 250ºC(decomposition). Highly soluble in water (1g soluble in 1mL20ºC water), slightly soluble in ethanol, insoluble in ether, benzene, chlorochemicalbook form and acetone. REDOX action can make it inactive. It has good thermal stability in air and acidic aqueous solution (pH 3.0 ~ 5.0), and is easy to decompose under neutral and alkaline conditions. Mouse transoral LD509.0g/kg.
