Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 380.48 g/mol gives Manidipine Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Manidipine Impurity 4 (CAS 89226-49-3) is a high-purity analytical reference standard with the molecular formula C23H28N2O3 and a molecular weight of 380.48 g/mol.
The molecular framework of Manidipine Impurity 4 (C23H28N2O3) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Manidipine Impurity 4 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.
