Chemical Structure
Description
Darifenacin Vinylbenzofuran Impurity (CAS 633335-98-5), molecular formula C10H8O and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Darifenacin Vinylbenzofuran Impurity (C10H8O) contains a hydroxyl group, an ether linkage, an aromatic ring system. 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 144.17 g/mol, it falls into the low-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.
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 Darifenacin Vinylbenzofuran 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.
