Chemical Structure
Description
As a certified reference material (CRM), 7-Chloro-3-cyclopentyl-3h-[1,2,3]triazolo[4,5-d]pyrimidine 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.
7-Chloro-3-cyclopentyl-3h-[1,2,3]triazolo[4,5-d]pyrimidine (CAS 14054-48-9) is a high-purity analytical reference standard with the molecular formula C9H10ClN5 and a molecular weight of 223.66 g/mol.
The molecular framework of 7-Chloro-3-cyclopentyl-3h-[1,2,3]triazolo[4,5-d]pyrimidine (C9H10ClN5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
