Chemical Structure

Levocarnitine Impurity N8 CAS 51499-71-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 137.56 g/mol gives Levocarnitine Impurity N8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Levocarnitine Impurity N8 (CAS 51499-71-9), a pharmacopoeial impurity reference standard (molecular formula C4H8ClNO2, MW 137.56 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C4H8ClNO2, Levocarnitine Impurity N8 contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 137.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
