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.
cis-4-[2-(2-Methoxyphenyl)-2-oxoethyl]-cyclohexane-1-carboxylic acid (CAS 735275-50-0), molecular formula C16H20O4 and molecular weight 276.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of cis-4-[2-(2-Methoxyphenyl)-2-oxoethyl]-cyclohexane-1-carboxylic acid (C16H20O4) 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 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 cis-4-[2-(2-Methoxyphenyl)-2-oxoethyl]-cyclohexane-1-carboxylic acid 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.
