2-(2-Nitrobenzylidene)-3-oxobutanoic Acid, 2-Acetoxy-2-methylpropyl Ester-d6 CAS 1185235-10-2

Description

2-(2-Nitrobenzylidene)-3-oxobutanoic Acid, 2-Acetoxy-2-methylpropyl Ester-d6 (CAS 1185235-10-2), molecular formula C17H13D6NO7 and molecular weight 355.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(2-Nitrobenzylidene)-3-oxobutanoic Acid, 2-Acetoxy-2-methylpropyl Ester-d6 (C17H13D6NO7) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
