2-((4-Methyl-2-oxo-2H-chromen-6-yl)oxy)propanoic acid CAS 96078-22-7

Description

The occurrence of 2-((4-Methyl-2-oxo-2H-chromen-6-yl)oxy)propanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((4-Methyl-2-oxo-2H-chromen-6-yl)oxy)propanoic acid (CAS 96078-22-7), molecular formula C13H12O5 and molecular weight 248.23 g/mol, is a CATO reference standard with documented purity and traceability.

2-((4-Methyl-2-oxo-2H-chromen-6-yl)oxy)propanoic acid (C13H12O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
