(4-Isopropylphenyl)(2-nitro-5-(prop-2-yn-1-yloxy)phenyl)methanone CAS 478965-00-3

Description

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.

(4-Isopropylphenyl)(2-nitro-5-(prop-2-yn-1-yloxy)phenyl)methanone (CAS 478965-00-3) is a high-purity analytical reference standard with the molecular formula C19H17NO4 and a molecular weight of 323.34 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (4-Isopropylphenyl)(2-nitro-5-(prop-2-yn-1-yloxy)phenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.34 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.
