Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(4-Chlorobenzenesulfinyl)methyl]-2-(pyridin-2-yl)-6-(pyrrolidin-1-yl)pyrimidine.
4-[(4-Chlorobenzenesulfinyl)methyl]-2-(pyridin-2-yl)-6-(pyrrolidin-1-yl)pyrimidine (CAS 306980-36-9) is a high-purity analytical reference standard with the molecular formula C20H19ClN4OS and a molecular weight of 398.91 g/mol.
The molecular framework of 4-[(4-Chlorobenzenesulfinyl)methyl]-2-(pyridin-2-yl)-6-(pyrrolidin-1-yl)pyrimidine (C20H19ClN4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
