Chemical Structure

2,4-Dihydroxybenzaldehyde CAS 95-01-2 chemical structure

Description

2,4-Dihydroxybenzaldehyde (CAS 95-01-2), molecular formula C7H6O3 and molecular weight 138.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2,4-Dihydroxybenzaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 2,4-Dihydroxybenzaldehyde 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.
