Anwendungen & Verwendung
Beschreibung
Glyoxylic acid monohydrate is a versatile chemical used in various pharmaceuticals, agrochemicals, and cosmetics industries. It is commonly used as an intermediate in producing chemicals like vanillin, amino acids, and herbicides. It should be stored in a cool, dry place away from oxidizing agents and sources of ignition. Glyoxylic acid monohydrate may cause severe skin burns and eye damage, so it is essential to follow proper safety guidelines when handling it. The environmental impact of this product is minimal if it is disposed of according to local regulations.
Verwenden
