Chemical Structure

(E)-1-(2-(furan-2-yl)vinyl)-3-(4-methoxyphenyl)urea CAS 478031-01-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-1-(2-(furan-2-yl)vinyl)-3-(4-methoxyphenyl)urea.

(E)-1-(2-(furan-2-yl)vinyl)-3-(4-methoxyphenyl)urea (CAS 478031-01-5), molecular formula C14H14N2O3 and molecular weight 258.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (E)-1-(2-(furan-2-yl)vinyl)-3-(4-methoxyphenyl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
