Chemical Structure
Description
CATO manufactures 2,3-Dimethyl-4-methoxybenzophenone 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.
2,3-Dimethyl-4-methoxybenzophenone (CAS 134994-51-7), molecular formula C16H16O2 and molecular weight 240.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,3-Dimethyl-4-methoxybenzophenone (C16H16O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
