Chemical Structure
Description
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.
3-Carboethoxy-3-(4-methoxyphenyl)propiophenone (CAS 898775-64-9), molecular formula C19H20O4 and molecular weight 312.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Carboethoxy-3-(4-methoxyphenyl)propiophenone (C19H20O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 3-Carboethoxy-3-(4-methoxyphenyl)propiophenone 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.
