Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-Chloro-2-ethoxy-7-methyl-4H-pyrido[1,2-a]pyrimidin-4-one (CAS 88405-10-1), a certified reference material (molecular formula C11H11ClN2O2, MW 238.67 g/mol) for analytical method development and quality control.
The molecular framework of 3-Chloro-2-ethoxy-7-methyl-4H-pyrido[1,2-a]pyrimidin-4-one (C11H11ClN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 3-Chloro-2-ethoxy-7-methyl-4H-pyrido[1,2-a]pyrimidin-4-one 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.
