Glyoxylic Acid Monohydrate
Name: Glyoxylic Acid Monohydrate
CAS Number: 563-96-2
Molecular formula: C2H2O3·H2O
Molecular weight: 92.04
Packing: The glyoxylic acid monohydrate packaging bag is a PE bag and heat-sealed. Or packaged according to customer requirements.
Properties: Glyoxylic acid crystal, with the chemical formula C2H2O3·H2O, possesses a distinctive odor and a melting point ranging from 40 to 50°C. It readily dissolves in water but remains insoluble in ether, ethanol, and benzene. Upon brief exposure to air, it has the tendency to absorb moisture and transform into a corrosive slurry.

Usage
In the fragrance industry, it serves as a raw material for producing methyl vanillin and ethyl vanillin.
In the pharmaceutical industry, it is employed in synthesizing hypertension drug Atalol, D-tyrosine (a nationally prioritized pharmaceutical intermediate), broad-spectrum antibiotics, oral hydroxyampicillin, phenylacetone, amino acids, and other compounds. Additionally, it functions as an intermediate in producing varnish, dyes, plastics, and agricultural chemicals.
It finds application in synthesizing pharmaceutical products such as capsules and uracil, contributing to anti-ulcer properties, and is an intermediate for everyday chemical products.
