2-(Carboxy(hydroxy)methyl)-6-hydroxybenzo[d]oxazole CAS 1804037-94-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Carboxy(hydroxy)methyl)-6-hydroxybenzo[d]oxazole.

2-(Carboxy(hydroxy)methyl)-6-hydroxybenzo[d]oxazole (CAS 1804037-94-2), molecular formula C9H7NO5 and molecular weight 209.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-(Carboxy(hydroxy)methyl)-6-hydroxybenzo[d]oxazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 209.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
