2-Thioxo-2,3-dihydrobenzo[d]oxazole-5-carbonitrile CAS 93794-41-3

Description

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.

2-Thioxo-2,3-dihydrobenzo[d]oxazole-5-carbonitrile (CAS 93794-41-3), molecular formula C8H4N2OS and molecular weight 176.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H4N2OS, 2-Thioxo-2,3-dihydrobenzo[d]oxazole-5-carbonitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 176.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

As a certified reference material (CRM), 2-Thioxo-2,3-dihydrobenzo[d]oxazole-5-carbonitrile 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.
