Chemical Structure
Description
The occurrence of 3-bromo-5-{5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazin-3-yl}pyridine trihydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-bromo-5-{5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazin-3-yl}pyridine trihydrochloride (CAS 1803588-43-3), molecular formula C10H10BrN5HCl and molecular weight 316.59 g/mol, is a CATO reference standard with documented purity and traceability.
3-bromo-5-{5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazin-3-yl}pyridine trihydrochloride (C10H10BrN5HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. 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 3-bromo-5-{5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazin-3-yl}pyridine trihydrochloride 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.
