Chemical Structure
Description
The occurrence of (2Z)-2-Amino-3-[(E)-[(pyridin-2-yl)methylidene]amino]but-2-enedinitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2Z)-2-Amino-3-[(E)-[(pyridin-2-yl)methylidene]amino]but-2-enedinitrile (CAS 58259-75-9), molecular formula C10H7N5 and molecular weight 197.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, (2Z)-2-Amino-3-[(E)-[(pyridin-2-yl)methylidene]amino]but-2-enedinitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
