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-(2,4,6-Trimethoxyphenyl)but-3-en-2-one (CAS 42811-79-0), molecular formula C13H16O4 and molecular weight 236.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(2,4,6-Trimethoxyphenyl)but-3-en-2-one (C13H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 4-(2,4,6-Trimethoxyphenyl)but-3-en-2-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.
