Propionyl L-carnitine hydrochloride

Propionyl L-carnitine hydrochloride (CAS 119793-66-7), also known as Levocarnitine propionate hydrochloride and abbreviated as PLC, is the propionyl ester form of L-carnitine supplied as a stable hydrochloride salt.

It is used in pharmaceutical and nutraceutical applications as a bioavailable carnitine derivative that supports cellular energy metabolism, particularly in peripheral and cardiovascular tissue.

PLC is a primary active ingredient in prescription and OTC pharmaceutical formulations targeting peripheral arterial disease and chronic heart failure, where it appears in tablet and oral solution dosage forms.

In sports nutrition and functional food supplements, it is formulated into capsules, sachets, and fortified beverages aimed at endurance and recovery positioning for athletes and active consumers.

Contract manufacturers and formulators source it as a pharmaceutical intermediate for finished-dose production requiring documented purity and stability profiles during the manufacturing process.

Its compatibility with standard excipients also makes it suitable for combination nutraceutical products alongside CoQ10, B-vitamins, and other carnitine forms for synergistic health benefits.

Propionyl L-carnitine hydrochloride is supplied as a white crystalline powder. It is available in pharmaceutical-grade specifications, with USP and EP-aligned grades the most commonly requested.

Bulk quantities are typically offered in kilogram and multi-kilogram packaging suited to both clinical manufacturing and nutraceutical production runs for global distribution and supply chains.
