Chemical Structure

4-(Hydroxymethyl)-2,3-dimethylphenol CAS 67730-45-4 chemical structure

Description

4-(Hydroxymethyl)-2,3-dimethylphenol (CAS 67730-45-4) is a high-purity analytical reference standard with the molecular formula C9H12O2 and a molecular weight of 152.19 g/mol.

The molecular framework of 4-(Hydroxymethyl)-2,3-dimethylphenol (C9H12O2) 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).

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

As a certified reference material (CRM), 4-(Hydroxymethyl)-2,3-dimethylphenol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
