Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2E)-3-{[4-(phenylamino)phenyl]amino}-2-(1H-1,2,3,4-tetrazol-5-yl)prop-2-enenitrile (CAS 683799-78-2) is a high-purity analytical reference standard with the molecular formula C16H13N7 and a molecular weight of 303.32 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, (2E)-3-{[4-(phenylamino)phenyl]amino}-2-(1H-1,2,3,4-tetrazol-5-yl)prop-2-enenitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
