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 6,8-Dibromo-7-methyl-[1,2,4]triazolo[1,5-a]pyridine.
6,8-Dibromo-7-methyl-[1,2,4]triazolo[1,5-a]pyridine (CAS 2155875-36-6), molecular formula C7H5Br2N3 and molecular weight 290.94 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6,8-Dibromo-7-methyl-[1,2,4]triazolo[1,5-a]pyridine (C7H5Br2N3) is characterized by a nitrile group, bromine 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 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), 6,8-Dibromo-7-methyl-[1,2,4]triazolo[1,5-a]pyridine 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.
