Description
CATO manufactures 1-(3-Chlorophenyl)prop-2-yn-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.
1-(3-Chlorophenyl)prop-2-yn-1-one (CAS 33899-25-1), molecular formula C9H5ClO and molecular weight 164.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(3-Chlorophenyl)prop-2-yn-1-one (C9H5ClO) 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.
