L-Carnitine L-tartrate

L-Carnitine L-Tartrate, abbreviated LCLT in the trade, is the crystalline salt formed from two molecules of levocarnitine and one molecule of L-(+)-tartaric acid: CAS 36687-82-8, molecular weight 472.48. Chemically it is the same entity as the L-carnitine tartrate listed elsewhere in this catalogue. The LCLT designation is what the sports-nutrition trade uses, and it signals the stereochemically specified salt built from levo carnitine and natural L-(+)-tartaric acid rather than any racemic or DL material. Assay is expressed as its two parts: 67.2 to 69.2% L-carnitine and 30.8 to 32.8% L-tartaric acid. In practice 1,000 mg of LCLT delivers about 680 mg of L-carnitine, which is the conversion to work from when turning a label claim into a batch sheet. Specific rotation runs -9.5 to -11.0 degrees at 10% in water, moisture sits at 0.5% maximum, and the salt is materially less hygroscopic than levocarnitine free base, which is what lets it hold up in pre-workout and recovery blends alongside other hygroscopic actives. It dissolves freely to a clear acidic solution at pH 3.0 to 4.5, and granulated grades are available where direct compression or low dusting matters. The levocarnitine is made either by chemical synthesis with chiral resolution or by microbial biotransformation of achiral precursors such as gamma-butyrobetaine or crotonobetaine using Escherichia coli or Proteus strains, so no animal-derived raw material is involved and the powder suits vegetarian and vegan positioning.
