Glyoxal
Molecular formula: C2H2O2
CAS NO.: 107-22-2
Molecular Weight: 58.04
Quality level: Q/GHNH 1-2007
Physical Property:
Low Acidity Glyoxal (40% aqueous) is colourless to pale yellow solution. In the air, the substance polymerizes easily; Heated, the polymer is decomposes glyoxal monomer.
Specification requirements:
Appearance: Colourless to pale yellow transparent liquid.
Usage: The industrial glyoxal usually exists by watery solution of 40% content. It is an important fine chemical product which is widely used in medicine and agriculture. Its sub-products include: 2- methyl imidazole, imidazole, 2- methyl -5- nitryl imidazole, meth-nitrylzole, dimeizole, clotrimazole; They also include glyoxalic acid with its sub-products of hordenine glycine, hordenine mattress, hordenine ethanoic acid and so on; They can also applied in industry, papermaking, spinning and weaving, leather processing, dying, water treatment, building materials and national defense...
