Chemical Structure

2,4,6-Trihydroxybenzoic Acid Monohydrate CAS 71989-93-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 188.13 g/mol gives 2,4,6-Trihydroxybenzoic Acid Monohydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,4,6-Trihydroxybenzoic Acid Monohydrate (CAS 71989-93-0), molecular formula C7H6O5H2O and molecular weight 188.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,4,6-Trihydroxybenzoic Acid Monohydrate (C7H6O5H2O) is characterized by a carbohydrate-derived structure. 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.
