Chemical Structure
Description
The occurrence of Levocarnitine Impurity N9 is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Levocarnitine Impurity N9 (CAS 251460-19-2), a pharmacopoeial impurity reference standard (molecular formula C6H16NO2Cl, MW 169.65 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Levocarnitine Impurity N9 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Levocarnitine Impurity N9 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
