Description
CATO supplies 4-[(E)-(3-Methyl-4-phenyl-1H-pyrazol-5-yl)diazenyl]-1H-pyrazole-3,5-diamine (CAS 1092839-72-9), a certified reference material (molecular formula C13H14N8, MW 282.30 g/mol) for analytical method development and quality control.
Structurally, 4-[(E)-(3-Methyl-4-phenyl-1H-pyrazol-5-yl)diazenyl]-1H-pyrazole-3,5-diamine (C13H14N8) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 282.30 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
