Chemical Structure

Levocarnitine EP Impurity A Chloride（E-Isomer） CAS 144205-67-4 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 Levocarnitine EP Impurity A Chloride（E-Isomer）.

Levocarnitine EP Impurity A Chloride（E-Isomer） (CAS 144205-67-4) is a certified pharmaceutical impurity reference standard with the molecular formula C7H14NO2Cl and a molecular weight of 179.64 g/mol.

Levocarnitine EP Impurity A Chloride（E-Isomer） (C7H14NO2Cl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
