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 6-Chloro-5,7-dihydro-4H-purin-2-amine.
CATO supplies 6-Chloro-5,7-dihydro-4H-purin-2-amine (CAS 851212-98-1), a certified reference material (molecular formula C5H6ClN5, MW 171.59 g/mol) for analytical method development and quality control.
6-Chloro-5,7-dihydro-4H-purin-2-amine (C5H6ClN5) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 6-Chloro-5,7-dihydro-4H-purin-2-amine 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.
