4-(sec-Butyl)-2-(1,1,2,2-tetrafluoroethyl)oxazol-5(2H)-one CAS 51314-52-4 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 4-(sec-Butyl)-2-(1,1,2,2-tetrafluoroethyl)oxazol-5(2H)-one.

CATO supplies 4-(sec-Butyl)-2-(1,1,2,2-tetrafluoroethyl)oxazol-5(2H)-one (CAS 51314-52-4), a certified reference material (molecular formula C9H11F4NO2, MW 241.18 g/mol) for analytical method development and quality control.

The molecular framework of 4-(sec-Butyl)-2-(1,1,2,2-tetrafluoroethyl)oxazol-5(2H)-one (C9H11F4NO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-(sec-Butyl)-2-(1,1,2,2-tetrafluoroethyl)oxazol-5(2H)-one 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.
