Levocarnitine impurity 25 CAS CATO-C4X-129225

Description

Compared with other compounds in its class, the molecular weight of 247.24 g/mol gives Levocarnitine impurity 25 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Levocarnitine impurity 25 (CAS CATO-C4X-129225), a pharmacopoeial impurity reference standard (molecular formula C7H14NO5SNa, MW 247.24 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C7H14NO5SNa, Levocarnitine impurity 25 contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 247.24 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.

As a certified reference material (CRM), Levocarnitine impurity 25 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
