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 (5-Bromo-2-chlorophenyl)(methyl)sulfane.
(5-Bromo-2-chlorophenyl)(methyl)sulfane (CAS 740806-64-8), molecular formula C7H6BrClS and molecular weight 237.54 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system, (5-Bromo-2-chlorophenyl)(methyl)sulfane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.54 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 (5-Bromo-2-chlorophenyl)(methyl)sulfane 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.
