Glyoxylic acid CAS 298-12-4
Glyoxylic acid CAS no 298-12-4 , also known as formoic acid, hydrated glyoxylic acid and oxyacetic acid, chemical formula C2H203, is the simplest aldehyde acid, which exists in immature fruits, tender green leaves and sugar beets. Crystals from water are monoclinic crystals (containing 1/2 crystal water). The relative molecular weight is 70.04. The melting point is 98 ℃. Glyoxylic acid has an unpleasant taste. Glyoxylic acid is a strong corrosive acid, which is easy to deliquescence and can form a paste when exposed to the air. Glyoxylic acid is slightly soluble in ethanol, ether and benzene, and can be freely soluble in water. The aqueous solution is stable and does not deteriorate in air. Glyoxylic acid solution exists in aqueous solution in the form of hydration. Glyoxylic acid can react with most metals except stainless steel. Glyoxylic acid solution has the properties of acid and aldehyde.
Glyoxylic acid (CAS 298-12-4) does not have a fixed and unified purity standard. Its purity needs to be classified according to the specific form (crystal or aqueous solution) and application scenario. We can provide two mainstream specifications: glyoxylic acid 98%min (crystal) and glyoxylic acid 50% (aqueous solution).

1. Glyoxylic acid CAS 298-12-4 used as material for methyl vanillin, ethyl vanillin in flavor industry.
2. Glyoxylic acid CAS 298-12-4 used as intermediate for D-hydroxybenzeneglycin, broadspectrum antibiotic, ,acetophenone ,amino acid etc.
3. Glyoxylic acid CAS 298-12-4 used as intermediate of varnish material, dyes, plastic, agrochemical, allantoin and daily-use chemical etc. Glyoxylic acid is popular in the cosmetic industry, glyoxylic acid for hair dye; hair care product; skin care product ect, but glyoxylic acid in hair products works really well.
4. Glyoxylic acid is the material for water purificants, pesticides. Glyoxylic acid is used as an intermediate of varnish material and dyes.
5. Glyoxylic acid CAS 298-12-4 also can be used in the preservation of food, as a crosslinking agent of polymerization and as a plating additive.
1.We produce glyoxylic acid solution with a purity of 50%min and solid with a purity of 98%min. Customers can choose according to their needs and production processes.
If the customer has requirements for the purity of glyoxylic acid solution, we can also customize different purities for the customer, such as 40%min.
2. The color number of glyoxylic acid liquid can be controlled. According to different customer needs (cosmetic additives, hair straightening formulas, aromatic components, etc.), the color number can be selected below 50, below 100, and below 300
3. Both glyoxylic acid solution and solid do not contain glyoxal. Many customers for hair straightening and hair care applications specifically require this spec.Because Glyoxal is actually considered an impurity, its presence can have a significant impact on product quality and color.UNILONG's glyoxylic acid CAS 298 12 4 products have received unanimous praise from customers.
