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-Chloro-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol.
CATO supplies 4-Chloro-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol (CAS 1545252-75-2), a certified reference material (molecular formula C7H7ClN2O, MW 170.60 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol (C7H7ClN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
CATO manufactures 4-Chloro-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol 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.
