Chemical Structure
Description
As a certified reference material (CRM), Ethyl 2-(2-amino-6-chloro-9H-purin-9-yl)acetate 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.
Ethyl 2-(2-amino-6-chloro-9H-purin-9-yl)acetate (CAS 213552-03-5) is a high-purity analytical reference standard with the molecular formula C9H10ClN5O2 and a molecular weight of 255.66 g/mol.
The molecular framework of Ethyl 2-(2-amino-6-chloro-9H-purin-9-yl)acetate (C9H10ClN5O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
