4-(4-cyano-2-methoxyphenoxy)butanoic acid CAS 1016499-74-3

Description

Compared with other compounds in its class, the molecular weight of 235.24 g/mol gives 4-(4-cyano-2-methoxyphenoxy)butanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(4-cyano-2-methoxyphenoxy)butanoic acid (CAS 1016499-74-3), a certified reference material (molecular formula C12H13NO4, MW 235.24 g/mol) for analytical method development and quality control.

4-(4-cyano-2-methoxyphenoxy)butanoic acid (C12H13NO4) contains an amino-acid-derived structure, 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.
