Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
3-(2-Chlorobenzyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-amine (CAS 832112-89-7), molecular formula C11H9ClN6 and molecular weight 260.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(2-Chlorobenzyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-amine (C11H9ClN6) 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.
As a certified reference material (CRM), 3-(2-Chlorobenzyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-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.
