542-81-4 2-Chloroethyl methyl sulfide 2-Chloroethyl methyl sulphide Ethane, 1-chloro-2-(methylthio)- (9CI) Sulfide, 2-chloroethyl methyl (8CI) 1-Chloro-2-(methylthio)ethane EINECS 208-828-6 2-Methylthioethyl chloride NSC 91724 (CAS 542-81-4) is a high-purity analytical reference standard with the molecular formula C3H7ClS and a molecular weight of 110.61 g/mol.
Structurally, 542-81-4 2-Chloroethyl methyl sulfide 2-Chloroethyl methyl sulphide Ethane, 1-chloro-2-(methylthio)- (9CI) Sulfide, 2-chloroethyl methyl (8CI) 1-Chloro-2-(methylthio)ethane EINECS 208-828-6 2-Methylthioethyl chloride NSC 91724 (C3H7ClS) contains sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 110.61 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
