Chemical Structure

2-(Difluoromethoxy)-7-mercaptobenzo[d]oxazole CAS 1806281-92-4 chemical structure

Description

The occurrence of 2-(Difluoromethoxy)-7-mercaptobenzo[d]oxazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Difluoromethoxy)-7-mercaptobenzo[d]oxazole (CAS 1806281-92-4) is a high-purity analytical reference standard with the molecular formula C8H5F2NO2S and a molecular weight of 217.19 g/mol.

Based on its molecular formula C8H5F2NO2S, 2-(Difluoromethoxy)-7-mercaptobenzo[d]oxazole contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 217.19 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).

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), 2-(Difluoromethoxy)-7-mercaptobenzo[d]oxazole 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.
