Chemical Structure

Fingolimod Impurity 18 CAS 1068-90-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Fingolimod Impurity 18.

CATO supplies Fingolimod Impurity 18 (CAS 1068-90-2), a pharmacopoeial impurity reference standard (molecular formula C9H15NO5, MW 217.22 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C9H15NO5, Fingolimod Impurity 18 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 217.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
