Chemical Structure
Description
3-Phenyl-4,5,6,7-tetrahydro-1,2,3-triazolo[1,5-a]pyrazine Hydrochloride (CAS 1245782-72-2), molecular formula C11H12N4HCl and molecular weight 236.70 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H12N4HCl, 3-Phenyl-4,5,6,7-tetrahydro-1,2,3-triazolo[1,5-a]pyrazine Hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 3-Phenyl-4,5,6,7-tetrahydro-1,2,3-triazolo[1,5-a]pyrazine Hydrochloride 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.
