L-carnitine, also known as levocarnitine, is a defined chiral biochemical compound rather than a peptide. Each vial contains measured dry laboratory material prepared to support consistent scientific handling, storage and analytical investigation. The stated nominal amount refers to the declared L-carnitine content of a single vial, subject to the applicable batch documentation. Where dissolution is required, the solvent, concentration, handling procedure and storage conditions stated in the applicable Certificate of Analysis, Safety Data Sheet or validated laboratory method should be followed. We do not provide advice or recommendations concerning dosage, administration or use in humans or animals.

L-Carnitine Product Overview

Our L-Carnitine research-grade biochemical compound, also known as levocarnitine, is supplied for controlled scientific laboratory investigation, analytical method development, biochemical characterisation, high-performance liquid chromatography assessment, mass-spectrometry workflows, formulation studies and reference-material comparison. The material is the R-configured L-enantiomer of carnitine and exists as a zwitterionic quaternary ammonium inner salt.

The material is handled with a focus on batch traceability, documented quality control and consistent laboratory presentation. Product identity, stereochemical identity, assay, chromatographic purity, molecular form, water content, residual solvents, inorganic residues, bacterial endotoxin results and other analytical specifications should be confirmed using the applicable batch Certificate of Analysis.

The CAS number 541-15-1, molecular formula C₇H₁₅NO₃ and average molecular weight of approximately 161.20 g/mol describe the uncountered zwitterionic L-carnitine inner salt. Where the supplied material is L-carnitine hydrochloride, L-carnitine tartrate or another salt form, the applicable batch documentation should identify the correct chemical form, molecular formula and formula weight.

For the majority of routine analytical, biochemical, formulation and general laboratory work, the Regular L-Carnitine specification remains highly suitable. The premium black-and-gold ULTIMATE L-Carnitine option provides an additional preparative high-performance liquid chromatography purification stage and a more stringent bacterial endotoxin and lipopolysaccharide testing specification for scientific projects requiring enhanced quality-control parameters.
