2-Hydroxy-3,6-dimethoxybenzaldehyde CAS 64466-51-9

Description

The occurrence of 2-Hydroxy-3,6-dimethoxybenzaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Hydroxy-3,6-dimethoxybenzaldehyde (CAS 64466-51-9), molecular formula C9H10O4 and molecular weight 182.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Hydroxy-3,6-dimethoxybenzaldehyde (C9H10O4) 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).

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.
