Description
CATO manufactures 2-(difluoromethyl)benzo[d]oxazole-4-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
2-(difluoromethyl)benzo[d]oxazole-4-carbonitrile (CAS 1806282-45-0), molecular formula C9H4F2N2O and molecular weight 194.14 g/mol, is a CATO reference standard with documented purity and traceability.
2-(difluoromethyl)benzo[d]oxazole-4-carbonitrile (C9H4F2N2O) 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
