Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl-2,4,5-Trichlorophenylsulfide.
Methyl-2,4,5-Trichlorophenylsulfide (CAS 4163-78-4) is a high-purity analytical reference standard with the molecular formula C7H5Cl3S and a molecular weight of 227.54 g/mol.
Owing to sulfur-containing functionality, chlorine substitution, an aromatic ring system, Methyl-2,4,5-Trichlorophenylsulfide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 227.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-2,4,5-Trichlorophenylsulfide 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.
