Chemical Structure

2-(Difluoromethyl)benzo[d]oxazole-6-carboxaldehyde CAS 1806396-07-5 chemical structure

Description

2-(Difluoromethyl)benzo[d]oxazole-6-carboxaldehyde (C9H5F2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

2-(Difluoromethyl)benzo[d]oxazole-6-carboxaldehyde (CAS 1806396-07-5) is a high-purity analytical reference standard with the molecular formula C9H5F2NO2 and a molecular weight of 197.14 g/mol.

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-(Difluoromethyl)benzo[d]oxazole-6-carboxaldehyde 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.
