L-Carnitine is a naturally occurring quaternary ammonium compound biosynthesized from lysine and methionine. It plays an essential role in fatty acid metabolism by transporting long-chain fatty acyl groups from the cytoplasm into the mitochondrial matrix for beta-oxidation. L-Carnitine is endogenously synthesized and also obtained from dietary sources.

Frequently Asked Questions
L-carnitine 600mg is verified at ≥99.5% purity via reverse-phase HPLC analysis. Each batch also undergoes ESI mass spectrometry for identity confirmation, LAL endotoxin testing (<0.1 EU/mg), and USP <71> sterility testing. A batch-specific Certificate of Analysis (COA) is included with every order.
Add bacteriostatic water (0.9% benzyl alcohol) slowly to the vial wall. Gently swirl to dissolve — do not shake or vortex. Solubility: Very soluble in water (>250 mg/mL). Reconstituted peptide should be stored at 2-8°C and used within 30 days. For single-use applications, sterile water may be substituted (no preservative, use immediately).
Lyophilized (powder): Store at -20°C, protected from light and moisture. Shelf life: 24 months. Reconstituted (solution): Store at 2-8°C, use within 30 days. Critical: Allow the vial to reach room temperature before opening to prevent moisture condensation inside the vial. Avoid repeated freeze-thaw cycles (max 3 recommended).
The CAS registry number for L-carnitine 600mg is 541-15-1. Molecular weight: 161.20 g/mol. Molecular formula: C7H15NO3. Full chemical characterization data including PubChem identifiers, SMILES notation, and InChIKey are available on the Chemical Properties tab above.
Yes. Every batch of L-carnitine 600mg is independently tested by Janssen Analytical Laboratories (ISO 17025-accredited). Testing includes HPLC purity analysis, mass spectrometry identity confirmation, LAL kinetic turbidimetric endotoxin assay, and USP <71> sterility testing. Full results are provided in the batch-specific COA. Additional documentation is available on the COA/HPLC/MS and 3rd Party Testing tabs above.
