(E)-2-(3-Amino-5-oxofuran-2(5H)-ylidene)acetonitrile CAS 19459-07-5

Description

Compared with other compounds in its class, the molecular weight of 136.11 g/mol gives (E)-2-(3-Amino-5-oxofuran-2(5H)-ylidene)acetonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (E)-2-(3-Amino-5-oxofuran-2(5H)-ylidene)acetonitrile (CAS 19459-07-5), a certified reference material (molecular formula C6H4N2O2, MW 136.11 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (E)-2-(3-Amino-5-oxofuran-2(5H)-ylidene)acetonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.11 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.

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.
