Chemical Structure

3,5-Bis(methoxycarbonyl)benzoic acid CAS 38588-64-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 238.19 g/mol gives 3,5-Bis(methoxycarbonyl)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,5-Bis(methoxycarbonyl)benzoic acid (CAS 38588-64-6), molecular formula C11H10O6 and molecular weight 238.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,5-Bis(methoxycarbonyl)benzoic acid (C11H10O6) 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 the polarity and ionization state of its functional groups, 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
