What is sodium mercaptide?
Sodium methyl mercaptide is methyl mercaptan in alkaline solution. Arkema is offering SMM 21% grade, in ISO or drums. We have also developed a SMM 33% grade which improve synthesis reaction yields. Moreover this grade supplied in specific ISOs is more competitive as logistic costs are lower.
What is a mercaptide?

What are mercaptans in garlic?
Allyl mercaptan (AM) is a small molecule allyl derivative and an organosulfur compound derived from garlic and a few other genus Allium plants. Its formula is C3H6S. It has been shown to be the most effective HDAC inhibitor of known garlic-derived organosulfur compounds and their metabolites.
Where are mercaptans found?
It is found in coal tar and petroleum distillates and as an emission from paper and pulp mills. Methyl mercaptan occurs naturally in some foods (e.g., onions, radishes, asparagus, some nuts and cheese).
Is methyl tin mercaptide hazardous?

What is the pKa of CH3SH?
~10.4
The chemical formula for methanethiol is CH3SH; it is classified as a thiol. Methanethiol is also considered to be a weak acid, with a pKa of ~10.4.
How are sodium Mercaptides made?
Stanley R. Sandler, Wolf Karo, in Sourcebook of Advanced Organic Laboratory Preparations, 1992 Sodium mercaptides are prepared from the mercaptans and aqueous or alcoholic solutions of sodium hydroxide or alcoholic sodium ethoxide.
Why are sodium Mercaptides more acidic than alcohols?
Sodium mercaptides are hydrolysed by water but the reaction is reversible, thiols being sufficiently acidic to dissolve in an excess of aqueous alkali. The greater acidity of thiols compared to alcohols is consistent with the fact that H 2 S is a stronger acid than H 2 O.
What is the chemical name of sodium acetate?
Sodium acetate is an organic sodium salt. It contains an acetate. Sodium Acetate is chemically designated CH3COONa, a hygroscopic powder very soluble in water.
What is sodium acetate injection used for?
Sodium Acetate Injection, USP (2 mEq/mL) is indicated as a source of sodium for addition to large volume intravenous fluids to prevent or correct hyponatremia in patients with restricted or no oral intake.
