Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 400.94 g/mol gives Methyl 2-[({2-[(4-chlorophenyl)sulfanyl]phenyl}methyl)sulfanyl]benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 2-[({2-[(4-chlorophenyl)sulfanyl]phenyl}methyl)sulfanyl]benzoate (CAS 337923-73-6) is a high-purity analytical reference standard with the molecular formula C21H17ClO2S2 and a molecular weight of 400.94 g/mol.
The molecular framework of Methyl 2-[({2-[(4-chlorophenyl)sulfanyl]phenyl}methyl)sulfanyl]benzoate (C21H17ClO2S2) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures Methyl 2-[({2-[(4-chlorophenyl)sulfanyl]phenyl}methyl)sulfanyl]benzoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
