Levocarnitine Impurity N25 CAS 51314-34-2

Description

Compared with other compounds in its class, the molecular weight of 193.67 g/mol gives Levocarnitine Impurity N25 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Levocarnitine Impurity N25 (CAS 51314-34-2), a pharmacopoeial impurity reference standard (molecular formula C8H16ClNO2, MW 193.67 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Levocarnitine Impurity N25 (C8H16ClNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), Levocarnitine Impurity N25 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.
