CAS 10387-40-3 Potassium thioacetate
Overview
Potassium thioacetate (KSAc, CAS 10387-40-3, C₂H₃KOS, 114.21 g/mol) is an efficient nucleophilic sulfur reagent used to install thioacetate groups via clean S_N2 displacement of alkyl halides or sulfonates, giving S-alkyl thioacetates that are readily deprotected to thiols under basic or hydrolytic conditions—useful across pharma, agrochemical, and polymer routes. Supplied as a white, hygroscopic solid, it is soluble in water, methanol, and other polar solvents (e.g., DMF/DMSO); avoid acids and strong oxidants (risk of H₂S), and store tightly closed in a dry, inert environment.

Product Description
CAS 10387-40-3 Potassium thioacetate
Chlorodiphenylphosphine (Ph₂PCl, CAS 1079-66-9) is an aryl P(III) chlorophosphine used to build tertiary phosphines (Ph₂PR), phosphonium salts, and other P-containing ligands/intermediates via clean nucleophilic substitution at the electrophilic P–Cl center (with R-MgX/R-Li, amines, or alcohols to form P–C/P–N/P–O bonds). Supplied as a colorless to pale-yellow liquid/low-melting solid, it dissolves in toluene, THF, CH₂Cl₂ (insoluble in water) and supports scalable processing under aprotic, anhydrous conditions.
