4-Ethylbenzo[d]oxazole-2-thiol CAS 915151-24-5

Description

The occurrence of 4-Ethylbenzo[d]oxazole-2-thiol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Ethylbenzo[d]oxazole-2-thiol (CAS 915151-24-5) is a high-purity analytical reference standard with the molecular formula C9H9NOS and a molecular weight of 179.24 g/mol.

The molecular framework of 4-Ethylbenzo[d]oxazole-2-thiol (C9H9NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.

As a certified reference material (CRM), 4-Ethylbenzo[d]oxazole-2-thiol 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.
