Chemical Structure
Description
CATO supplies (S)-2-(2-(tert-butoxy)-2-oxoethyl)-4,4-difluoropentanoic acid (CAS 1581718-78-6), a certified reference material (molecular formula C11H18F2O4, MW 252.26 g/mol) for analytical method development and quality control.
The molecular framework of (S)-2-(2-(tert-butoxy)-2-oxoethyl)-4,4-difluoropentanoic acid (C11H18F2O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
CATO manufactures (S)-2-(2-(tert-butoxy)-2-oxoethyl)-4,4-difluoropentanoic 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.
