Chemical Structure
Description
The occurrence of 3-(2-Fluorobenzyl)-3,6-dihydro-7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(2-Fluorobenzyl)-3,6-dihydro-7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one (CAS 119222-30-9), molecular formula C11H8FN5O and molecular weight 245.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(2-Fluorobenzyl)-3,6-dihydro-7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one (C11H8FN5O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 3-(2-Fluorobenzyl)-3,6-dihydro-7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one 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.
