Glyoxylic acid is an important organic chemical raw material, which exists in immature fruits and body fluids of some animal tissues. Glyoxylic acid, white columnar crystal, alias formaldehyde formic acid, dihydroxyacetic acid, oxyacetic acid, formaldehyde formic acid, formyl formic acid, etc., English name Glyoxylic acid, molecular formula C2H 23, relative molecular weight 74.04. The aqueous solution is a colourless transparent liquid. The melting point of hemihydrate is 70-75 C and that of anhydrous substance is 98 C. It is soluble in water, slightly soluble in ethanol, ether and benzene, and insoluble in esters and aromatic solvents. Its aqueous solution is stable in the air, glyoxylic acid exists in the form of hydrate in the aqueous solution, and commodities are often made into syrup-like or aqueous solutions of different concentrations.

Glyoxylic acid is the simplest aldehyde acid. There are two functional groups in the molecule, aldehyde group and carboxyl group. Therefore, glyoxylic acid has the properties of aldehyde and carboxylic acid, and has many reactivity. Glyoxylic acid, a commercially available commodity, usually occurs in the form of its aqueous solution. In the past, the content of glyoxylic acid was mostly 20%. At present, it generally refers to commodities with 40% or 50% content. Glyoxylic acid has the dual characteristics of aldehyde and acid. It can react with aldehyde and acid at the same time. Sometimes, cyclization or condensation reactions occur. As a result, dozens of fine chemical products with wide applications have been derived, and it is an important intermediate for organic synthesis.

So do you know the use of glyoxylic acid?

Glyoxylic acid is an important fine chemical raw material, which is widely used. In medicine, glyoxylic acid can be used to synthesize oral penicillin, allantoin (good healing agent for skin wounds, additives for high-grade cosmetics, plant growth regulators, etc.), p-hydroxyphenylglycine, p-hydroxyphenylacetic acid, mandelic acid, acetophenone, alpha-thiophenolic acid, p-hydroxyphenylacetamide (used as an effective agent for the treatment of cardiovascular diseases and hypertension-A. In spices, glyoxylic acid can be used to synthesize vanillin, ethyl vanillin, jasmonaldehyde (piperonal), p-methoxybenzaldehyde (anisaldehyde), etc. In pesticides, glyphosate can be used to produce glyphosate, glutaran, carbendazim, quinothion, foprofen, etc.
