Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[3-(4-Fluorophenyl)-2,1-benzoxazol-5-yl]ethan-1-one.
1-[3-(4-Fluorophenyl)-2,1-benzoxazol-5-yl]ethan-1-one (CAS 306978-23-4) is a high-purity analytical reference standard with the molecular formula C15H10FNO2 and a molecular weight of 255.24 g/mol.
1-[3-(4-Fluorophenyl)-2,1-benzoxazol-5-yl]ethan-1-one (C15H10FNO2) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-[3-(4-Fluorophenyl)-2,1-benzoxazol-5-yl]ethan-1-one 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.
