Chemical Structure
Description
CATO supplies 1,4-Bis(1,5-diphenyl-4,5-dihydro-1H-pyrazol-3-yl)benzene (CAS 7267-75-6), a certified reference material (molecular formula C36H30N4, MW 518.65 g/mol) for analytical method development and quality control.
Structurally, 1,4-Bis(1,5-diphenyl-4,5-dihydro-1H-pyrazol-3-yl)benzene (C36H30N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 518.65 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).
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 1,4-Bis(1,5-diphenyl-4,5-dihydro-1H-pyrazol-3-yl)benzene 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.
