Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(2-Acetoxyphenyl)-2-chloro-1-butene (CAS 890097-72-0), molecular formula C12H13ClO2 and molecular weight 224.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(2-Acetoxyphenyl)-2-chloro-1-butene (C12H13ClO2) 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 its high hydrophobicity (logP), 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.
CATO manufactures 4-(2-Acetoxyphenyl)-2-chloro-1-butene 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.
