Description

Compared with other compounds in its class, the molecular weight of 411.49 g/mol gives 1142205-53-5 9349AC C23H29N3O4 [{2-[4-(2,5-Dimethylphenyl)piperazin-1-yl]-2-oxoethyl}(4-methoxyphenyl)amino]acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1142205-53-5 9349AC C23H29N3O4 [{2-[4-(2,5-Dimethylphenyl)piperazin-1-yl]-2-oxoethyl}(4-methoxyphenyl)amino]acetic acid (CAS 1142205-53-5), molecular formula C23H29N3O4 and molecular weight 411.49 g/mol, is a CATO reference standard with documented purity and traceability.

1142205-53-5 9349AC C23H29N3O4 [{2-[4-(2,5-Dimethylphenyl)piperazin-1-yl]-2-oxoethyl}(4-methoxyphenyl)amino]acetic acid (C23H29N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
