Chemical Structure
Description
Structurally, (2Z)-2-Amino-3-[(E)-[(2,4-dichlorophenyl)methylidene]amino]but-2-enedinitrile (C11H6Cl2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 265.10 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies (2Z)-2-Amino-3-[(E)-[(2,4-dichlorophenyl)methylidene]amino]but-2-enedinitrile (CAS 74900-59-7), a certified reference material (molecular formula C11H6Cl2N4, MW 265.10 g/mol) for analytical method development and quality control.
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.
