Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(5-Chloro-2-methoxyphenyl)ethane-1-thiol.
2-(5-Chloro-2-methoxyphenyl)ethane-1-thiol (CAS 1267666-89-6), molecular formula C9H11ClOS and molecular weight 202.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-(5-Chloro-2-methoxyphenyl)ethane-1-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2-(5-Chloro-2-methoxyphenyl)ethane-1-thiol 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.
