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-(2,4-Dichloro-3-methylphenyl)ethanone.
CATO supplies 1-(2,4-Dichloro-3-methylphenyl)ethanone (CAS 157652-32-9), a certified reference material (molecular formula C9H8Cl2O, MW 203.07 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2,4-Dichloro-3-methylphenyl)ethanone (C9H8Cl2O) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-(2,4-Dichloro-3-methylphenyl)ethanone 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.
