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 3-Chloro-4-(phenylsulfanyl)aniline.
3-Chloro-4-(phenylsulfanyl)aniline (CAS 32631-26-8), molecular formula C12H10ClNS and molecular weight 235.73 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-4-(phenylsulfanyl)aniline (C12H10ClNS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 3-Chloro-4-(phenylsulfanyl)aniline 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.
