Chemical Structure

(2-ethyl-4-methyl-1,3-oxazol-5-yl)methanol CAS 137267-30-2 chemical structure

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (2-ethyl-4-methyl-1,3-oxazol-5-yl)methanol is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.17 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).

(2-ethyl-4-methyl-1,3-oxazol-5-yl)methanol (CAS 137267-30-2), molecular formula C7H11NO2 and molecular weight 141.17 g/mol, is a CATO reference standard with documented purity and traceability.

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.
