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 2-Chloro-9-ethyl-9H-purine.
CATO supplies 2-Chloro-9-ethyl-9H-purine (CAS 890093-92-2), a certified reference material (molecular formula C7H7ClN4, MW 182.61 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-9-ethyl-9H-purine (C7H7ClN4) is characterized by a nitrile group, 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. 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).
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), 2-Chloro-9-ethyl-9H-purine 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.
