Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-((4-Chlorophenyl)sulfonyl)-2-imino-1-(pyridin-3-ylmethyl)-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one.
3-((4-Chlorophenyl)sulfonyl)-2-imino-1-(pyridin-3-ylmethyl)-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (CAS 577764-47-7) is a high-purity analytical reference standard with the molecular formula C23H16ClN5O3S and a molecular weight of 477.92 g/mol.
The molecular framework of 3-((4-Chlorophenyl)sulfonyl)-2-imino-1-(pyridin-3-ylmethyl)-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (C23H16ClN5O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-((4-Chlorophenyl)sulfonyl)-2-imino-1-(pyridin-3-ylmethyl)-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
