Pharmaceutical Raw Materials powder Sodium bisulfite
Product Overview:
Sodium bisulfite powder is also known as sodium bisulfite. Sodium bisulfite CAS 7631-90-5 is a colorless monochromatic crystal or white crystalline powder, with sulfur dioxide odor, molecular weight 190.10, relative density 1.48, decomposition at the melting point, unstable in the air, the release of SO2. Sodium bisulfite Raw Materials are soluble in water and the aqueous solution is acidic. The solution also has strong reducibility. In case of acid, it decomposes and releases sulfur dioxide.
