Acetyl-L-Carnitine Hydrochloride

Acetyl L-carnitine hydrochloride (CAS 5080-50-2), commonly abbreviated as ALCAR, is the acetylated, salt form of L-carnitine.

Where is Acetyl-L-Carnitine Hydrochloride used?

• Dietary supplements: primary active ingredient in capsule, tablet, and powder formulations targeting cognitive support and energy metabolism
• Pharmaceuticals: active pharmaceutical ingredient and intermediate in finished-dose products
• Cosmetics and personal care: humectant and moisturizing agent in skin creams, serums, and anti-aging products
• Sports nutrition: pre-workout blends
• Functional beverages: carnitine bioavailability is a key formulation consideration.

Good to know: Acetylcarnitine hydrochloride delivers the acetyl group across biological membranes more readily than free carnitine, making it the preferred form for bioavailability-sensitive applications.

Commercial specifications

• Pharmaceutical-grade material meets compendial purity requirements relevant to finished-dose manufacturing
• Bulk quantities standard for nutraceutical and pharmaceutical procurement; smaller quantities for cosmetic and R&D applications
