Description

The occurrence of 2475-18-5 Arsine, bis(dodecylthio)methyl- Arsonodithious acid, methyl-, didodecyl ester (9CI) Methanearsonous acid, dithio-, didodecyl ester (8CI) BRN 2106585 Didodecyl dithiomethanearsonoate Didodecyl methylarsonodithioate MALS Methylarsine bis(lauryl sulfide) is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2475-18-5 Arsine, bis(dodecylthio)methyl- Arsonodithious acid, methyl-, didodecyl ester (9CI) Methanearsonous acid, dithio-, didodecyl ester (8CI) BRN 2106585 Didodecyl dithiomethanearsonoate Didodecyl methylarsonodithioate MALS Methylarsine bis(lauryl sulfide) (CAS 2475-18-5), molecular formula C25H53AsS2 and molecular weight 492.74 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2475-18-5 Arsine, bis(dodecylthio)methyl- Arsonodithious acid, methyl-, didodecyl ester (9CI) Methanearsonous acid, dithio-, didodecyl ester (8CI) BRN 2106585 Didodecyl dithiomethanearsonoate Didodecyl methylarsonodithioate MALS Methylarsine bis(lauryl sulfide) (C25H53AsS2) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 492.74 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
