Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(Difluoromethyl)benzo[d]oxazole-7-acetic acid (CAS 1804079-81-9), molecular formula C10H7F2NO3 and molecular weight 227.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(Difluoromethyl)benzo[d]oxazole-7-acetic acid (C10H7F2NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 227.16 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 2-(Difluoromethyl)benzo[d]oxazole-7-acetic acid 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.
