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 5,6,7,8-Tetrahydro-1,2,4-triazolo[4,3-a]pyrazine Dihydrochloride.
5,6,7,8-Tetrahydro-1,2,4-triazolo[4,3-a]pyrazine Dihydrochloride (CAS 1429056-45-0), molecular formula C5H8N4HCl and molecular weight 160.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5,6,7,8-Tetrahydro-1,2,4-triazolo[4,3-a]pyrazine Dihydrochloride (C5H8N4HCl) is characterized by a nitrile group, chlorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5,6,7,8-Tetrahydro-1,2,4-triazolo[4,3-a]pyrazine Dihydrochloride 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.
