Description
Carboxymethylmercaptosuccinic acid, also known as mercaptosuccinic acid or mercaptoundecanoic acid, is a water-soluble organic compound that features a carboxylic acid group and a thiol group. It is recognized for its chelating properties, which allow it to bind to metal ions effectively, forming stable complexes. This characteristic makes it a versatile ingredient in various industrial and pharmaceutical applications, including the production of food additives, cosmetics, and pharmaceuticals. Its ability to chelate metals such as calcium, magnesium, and zinc is particularly valuable in processes involving metal sequestration and metal chelation.

Used in Environmental Remediation:
Carboxymethylmercaptosuccinic acid has been studied for its potential role in environmental remediation, particularly in the treatment of wastewater and soil contaminated with heavy metals. Its chelating properties enable it to bind and remove toxic metal ions, reducing their environmental impact.
Used as a Corrosion Inhibitor in Metalworking Fluids:
In the metalworking industry, carboxymethylmercaptosuccinic acid is used as a corrosion inhibitor in metalworking fluids. Its ability to chelate metal ions helps to prevent the corrosion of metal surfaces during manufacturing processes, thereby extending the life of machinery and improving the quality of the finished products.
Check Digit Verification of cas no
The CAS Registry Mumber 99-68-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99-68:
(4*9)+(3*9)+(2*6)+(1*8)=83
83 % 10 = 3
So 99-68-3 is a valid CAS Registry Number.

Reductive coupling of aldehydes by H2S in aqueous solutions, a C-C bond forming reaction of prebiotic interest
Kajjout, Mohammed,Hebting, Yanek,Albrecht, Pierre,Adam, Pierre
experimental part, p. 714 - 726 (2012/07/14)
We report here a novel reductive coupling reaction of conjugated, non- or poorly enolizable aldehydes induced by H2S and operative in aqueous solutions under prebiotically relevant conditions. This reaction leads from retinal to β-carotene, and from benzylic aldehydes to the corresponding diarylethylenes. This novel reaction also opens a new potentially prebiotic pathway leading from glyoxylic acid to various compounds that are involved in the reductive tricarboxylic acid cycle. This C-C bond forming reaction of prebiotic interest might have been operative, notably, in the sulfide-rich environments of hydrothermal vents, which have been postulated as possible sites for the first steps of organic chemical evolution.
