Description
CATO manufactures Darifenacin(acetic Acid) Des-(5-Ethyl-2,3-dihydrobenzofuran) (Darifenacin Impurity) 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.
CATO supplies Darifenacin(acetic Acid) Des-(5-Ethyl-2,3-dihydrobenzofuran) (Darifenacin Impurity) (CAS 1050646-75-7), a certified reference material (molecular formula C18H19NO2, MW 281.35 g/mol) for analytical method development and quality control.
The molecular framework of Darifenacin(acetic Acid) Des-(5-Ethyl-2,3-dihydrobenzofuran) (Darifenacin Impurity) (C18H19NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
