Description
CATO manufactures 5,6,7,8-Tetrahydro-[1,2,4]triazolo[1,5-a]pyrazine hydrochloride 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.
CATO supplies 5,6,7,8-Tetrahydro-[1,2,4]triazolo[1,5-a]pyrazine hydrochloride (CAS 874360-12-0), a certified reference material (molecular formula C5H8N4HCl, MW 160.60 g/mol) for analytical method development and quality control.
5,6,7,8-Tetrahydro-[1,2,4]triazolo[1,5-a]pyrazine hydrochloride (C5H8N4HCl) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
