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 (S)-2-(1-(9H-Purin-6-ylamino)ethyl)-5-fluoro-3-phenylquinazolin-4(3H)-one.
(S)-2-(1-(9H-Purin-6-ylamino)ethyl)-5-fluoro-3-phenylquinazolin-4(3H)-one (CAS 870281-17-7) is a high-purity analytical reference standard with the molecular formula C21H16FN7O and a molecular weight of 401.40 g/mol.
The molecular framework of (S)-2-(1-(9H-Purin-6-ylamino)ethyl)-5-fluoro-3-phenylquinazolin-4(3H)-one (C21H16FN7O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 (S)-2-(1-(9H-Purin-6-ylamino)ethyl)-5-fluoro-3-phenylquinazolin-4(3H)-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.
