2-Nitro-5-(prop-2-yn-1-yloxy)benzyl 4-cyano-4-((phenylcarbonothioyl)thio)pentanoate CAS 1318075-32-9

Description

CATO supplies 2-Nitro-5-(prop-2-yn-1-yloxy)benzyl 4-cyano-4-((phenylcarbonothioyl)thio)pentanoate (CAS 1318075-32-9), a certified reference material (molecular formula C23H20N2O5S2, MW 468.55 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-Nitro-5-(prop-2-yn-1-yloxy)benzyl 4-cyano-4-((phenylcarbonothioyl)thio)pentanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 468.55 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.
