Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(3-Cyanophenyl)-2-[4-(5-ethyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidin-2-yl]acetamide.
N-(3-Cyanophenyl)-2-[4-(5-ethyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidin-2-yl]acetamide (CAS 1775484-71-3), molecular formula C21H20N6O4 and molecular weight 420.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(3-Cyanophenyl)-2-[4-(5-ethyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidin-2-yl]acetamide (C21H20N6O4) is characterized by a flavonoid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures N-(3-Cyanophenyl)-2-[4-(5-ethyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidin-2-yl]acetamide 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.
