Description

Dl-Carnitine CAS NO 406-76-8 is a synthetic, racemic mixture of the essential nutrient L-carnitine and its enantiomer D-carnitine. This compound is critical for the transport of long-chain fatty acids into the mitochondria for energy production via β-oxidation. It is widely utilized in the pharmaceutical, nutraceutical, and animal feed industries as a key ingredient for metabolic support, energy enhancement, and weight management formulations.

Application

• Pharmaceutical Intermediates: Serves as a key starting material or intermediate in the synthesis of specialized pharmaceutical actives targeting metabolic disorders.
• Dietary Supplements & Nutraceuticals: Incorporated into capsules, tablets, and powders aimed at improving exercise performance, supporting fat metabolism, and enhancing energy levels.
• Functional Food & Beverage Fortification: Used to enrich health-focused drinks, meal replacements, and food products with carnitine's metabolic benefits.
• Animal Nutrition & Feed Additives: Added to livestock, poultry, and aquaculture feed to improve growth performance, feed efficiency, and overall animal health.
• Cosmetic & Personal Care: Employed in topical formulations for its potential anti-aging and skin-conditioning properties.
• Research & Development: Used as a standard or reagent in biochemical, nutritional, and metabolic research studies.
