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 4,7-Dibromo-1h-[1,2,3]triazolo[4,5-c]pyridine.
4,7-Dibromo-1h-[1,2,3]triazolo[4,5-c]pyridine (CAS 1590410-83-5), molecular formula C5H2Br2N4 and molecular weight 277.90 g/mol, is a CATO reference standard with documented purity and traceability.
4,7-Dibromo-1h-[1,2,3]triazolo[4,5-c]pyridine (C5H2Br2N4) contains a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 4,7-Dibromo-1h-[1,2,3]triazolo[4,5-c]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.
