3-(Prop-2-yn-1-yl)benzo[d]oxazol-2(3H)-one CAS 19420-41-8

Description

The occurrence of 3-(Prop-2-yn-1-yl)benzo[d]oxazol-2(3H)-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(Prop-2-yn-1-yl)benzo[d]oxazol-2(3H)-one (CAS 19420-41-8), molecular formula C10H7NO2 and molecular weight 173.17 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, 3-(Prop-2-yn-1-yl)benzo[d]oxazol-2(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 173.17 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.
