Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 271.24 g/mol gives Vigabatrin Impurity 20 TFA Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Vigabatrin Impurity 20 TFA Salt (CAS 213758-47-5(free base)), a pharmacopoeial impurity reference standard (molecular formula C8H15NO2C2HF3O2, MW 271.24 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C8H15NO2C2HF3O2, Vigabatrin Impurity 20 TFA Salt contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 271.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
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.
