Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2Z)-2-Amino-3-[(E)-({5-nitro-2-[4-(trifluoromethyl)phenoxy]phenyl}methylidene)amino]but-2-enedinitrile.
CATO supplies (2Z)-2-Amino-3-[(E)-({5-nitro-2-[4-(trifluoromethyl)phenoxy]phenyl}methylidene)amino]but-2-enedinitrile (CAS 1024672-73-8), a certified reference material (molecular formula C18H10F3N5O3, MW 401.30 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H10F3N5O3, (2Z)-2-Amino-3-[(E)-({5-nitro-2-[4-(trifluoromethyl)phenoxy]phenyl}methylidene)amino]but-2-enedinitrile contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 401.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
