Chemical Structure

(E)-4-(dimethylamino)-2-(2-((((3-fluorobenzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)nicotinonitrile CAS 303986-43-8 chemical structure

Description

The occurrence of (E)-4-(dimethylamino)-2-(2-((((3-fluorobenzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)nicotinonitrile is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-4-(dimethylamino)-2-(2-((((3-fluorobenzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)nicotinonitrile (CAS 303986-43-8), a certified reference material (molecular formula C20H18FN5O, MW 363.39 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (E)-4-(dimethylamino)-2-(2-((((3-fluorobenzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)nicotinonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 363.39 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.

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.
