2-Hydroxy-2-(2,3,4-trimethoxyphenyl)acetic acid CAS 838902-26-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Hydroxy-2-(2,3,4-trimethoxyphenyl)acetic acid.

2-Hydroxy-2-(2,3,4-trimethoxyphenyl)acetic acid (CAS 838902-26-4), molecular formula C11H14O6 and molecular weight 242.23 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Hydroxy-2-(2,3,4-trimethoxyphenyl)acetic acid (C11H14O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 242.23 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
