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-4H-pyrazolo[1,5-a][1,4]diazepine-2-carbonitrile.
CATO supplies 5,6,7,8-Tetrahydro-4H-pyrazolo[1,5-a][1,4]diazepine-2-carbonitrile (CAS 1209685-62-0), a certified reference material (molecular formula C8H10N4HCl, MW 198.65 g/mol) for analytical method development and quality control.
5,6,7,8-Tetrahydro-4H-pyrazolo[1,5-a][1,4]diazepine-2-carbonitrile (C8H10N4HCl) contains a nitrogen-containing heterocyclic scaffold, 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.
As a certified reference material (CRM), 5,6,7,8-Tetrahydro-4H-pyrazolo[1,5-a][1,4]diazepine-2-carbonitrile 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.
