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 (S)-2-Chloro-1-(4-chlorophenyl)ethanol.
CATO supplies (S)-2-Chloro-1-(4-chlorophenyl)ethanol (CAS 178460-78-1), a certified reference material (molecular formula C8H8Cl2O, MW 191.05 g/mol) for analytical method development and quality control.
The molecular framework of (S)-2-Chloro-1-(4-chlorophenyl)ethanol (C8H8Cl2O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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 (S)-2-Chloro-1-(4-chlorophenyl)ethanol 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.
