relugolix Impurity 53 CAS 5806-90-6

Description

Compared with other compounds in its class, the molecular weight of 89.09 g/mol gives relugolix Impurity 53 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies relugolix Impurity 53 (CAS 5806-90-6), a pharmacopoeial impurity reference standard (molecular formula C3H7NO2, MW 89.09 g/mol) used for the identification and quantification of trace impurities in APIs.

relugolix Impurity 53 (C3H7NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
