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.

(1R,3R,4S,5R)-1,3-Bis[[3-(3,4-dihydroxyphenyl)propenoyl]oxy]-4,5-dihydroxycyclohexanecarboxylic acid 1,3-Dicaffeoylquinic acid 2,3-Dimethylphenylacetic acid 30981-98-7 (CAS 30981-98-7), molecular formula C10H12O2 and molecular weight 164.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (1R,3R,4S,5R)-1,3-Bis[[3-(3,4-dihydroxyphenyl)propenoyl]oxy]-4,5-dihydroxycyclohexanecarboxylic acid 1,3-Dicaffeoylquinic acid 2,3-Dimethylphenylacetic acid 30981-98-7 (C10H12O2) 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 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).

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.
