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 5-Bromo-8-methoxy-[1,2,4]triazolo[4,3-a]pyrazine.
CATO supplies 5-Bromo-8-methoxy-[1,2,4]triazolo[4,3-a]pyrazine (CAS 1334135-57-7), a certified reference material (molecular formula C6H5BrN4O, MW 229.03 g/mol) for analytical method development and quality control.
5-Bromo-8-methoxy-[1,2,4]triazolo[4,3-a]pyrazine (C6H5BrN4O) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 5-Bromo-8-methoxy-[1,2,4]triazolo[4,3-a]pyrazine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
