Chemical Structure

1-(4-Chlorophenyl)-2-methoxyethan-1-one CAS 30780-45-1 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 1-(4-Chlorophenyl)-2-methoxyethan-1-one.

CATO supplies 1-(4-Chlorophenyl)-2-methoxyethan-1-one (CAS 30780-45-1), a certified reference material (molecular formula C9H9ClO2, MW 184.62 g/mol) for analytical method development and quality control.

The molecular framework of 1-(4-Chlorophenyl)-2-methoxyethan-1-one (C9H9ClO2) is characterized by a carboxylic acid group, 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 1-(4-Chlorophenyl)-2-methoxyethan-1-one 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.
