Chemical Structure

Etrasimod Impurity 70 CAS CATO-C4X-321470 chemical structure

Description

Based on its molecular formula C12H13F3, Etrasimod Impurity 70 contains fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 214.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Etrasimod Impurity 70 (CAS CATO-C4X-321470) is a certified pharmaceutical impurity reference standard with the molecular formula C12H13F3 and a molecular weight of 214.23 g/mol.

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.
