What is glyoxylic acid ?

What is glyoxylic acid

Glyoxylic acid is composed of an aldehyde group (-CHO) and a carboxyl group (-COOH), and its structure is simple type HOCCOOH, molecular formula C2H2O3. A white crystal with unpleasant odors, and the aqueous solution is a colorless or pale yellow transparent liquid. Soluble in water, aqueous solution was yellow; insoluble in ether, ethanol and benzene. Exposure to the air in a short time that can absorb moisture into a slurry, corrosive. Toxic, can stimulate the skin and mucous membranes.

Application of glyoxylic acid

1 Produce Vanillin

Vanillin is a large amount of synthetic spices in the variety, widely used in food, tobacco and alcohol industry, most of the use of guaiacol and glyoxylic acid condensation, and then by high temperature oxidation hydrolysis decarboxylation for production

2 For the production of Allantoin preparations

Allantoin is not only a plant growth promoter, but also treats skin ulcer disease, as an advanced cosmetic additive.

3 Preparation of Ethyl vanillin

Ethyl guaiacol and glyoxylic acid as raw materials for the synthesis of ethyl vanillin is vanillin replacement products, the fragrance of vanillin 3 ~ 415 times, can be widely used in various types of food , Cosmetics, tobacco, wine which.


DL-4-HYDROXYPHENYLGLYCINE is the main raw material for the production of broad-spectrum antibiotic amoxicillin. At present, the global production of amoxicillin is about 10,000 t, the product has been identified as the World Health Organization recommended drugs, which makes its market demand soared.

5 Production of 4-Hydroxyphenylacetic acid

4-hydroxyphenylacetic acid can be used to produce antihypertensive drugs atenolol, the annual export volume of about 100t.

6 Application in Pharmaceutical Industry

Can be used in the pharmaceutical industry as oral penicillin, acetophenone, amino acids, Α 2 thiophene glycolic acid, p-hydroxyphenylacetamide intermediates;

7 Applications in pesticide

Can be used for the production of glyphosate, grass Trun, rare insects, quinophos, grass and so on,

8 Used in the production of water purification agent

Glyoxylic acid as raw material to produce hydroxy phosphoric acid is a good quality, industry associations recommend the development of the focus of the water purifier.

9 Glyoxylic acid can also be used directly for food storage and polymer synthesis process of cross-linking agent.

10.Glyoxylic acid can be used for hair care

hair care

In addition to the above application, glyoxylic acid as a more widely used fine chemical products, in many other aspects of the application is to be developed and explored. Such as intermediates for varnish raw materials, dyes, plastics and agrochemicals,

Production and life we are very dependent on glyoxylic acid, used as cosmetics, flavoring and fragrance for the pharmaceutical, which can make our lives more convenient.
