Description
CATO supplies 3-(4-(tert-Butyl)phenyl)-7-methyl-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidine (CAS 900888-79-1), a certified reference material (molecular formula C17H18N6, MW 306.37 g/mol) for analytical method development and quality control.
Structurally, 3-(4-(tert-Butyl)phenyl)-7-methyl-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidine (C17H18N6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 306.37 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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-(4-(tert-Butyl)phenyl)-7-methyl-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidine 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.
