Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-bromo-4-chloro-5H-pyrrolo[3,2-d]pyrimidine.
7-bromo-4-chloro-5H-pyrrolo[3,2-d]pyrimidine (CAS 1032650-41-1), molecular formula C6H11BrClN3 and molecular weight 240.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-bromo-4-chloro-5H-pyrrolo[3,2-d]pyrimidine (C6H11BrClN3) is characterized by a nitrile group, chlorine/bromine 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.
CATO manufactures 7-bromo-4-chloro-5H-pyrrolo[3,2-d]pyrimidine 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.
