Description

Dl-Carnitine is a racemic mixture of the essential amino acid derivative, L-carnitine, and its enantiomer, D-carnitine. This compound plays a vital role in cellular energy metabolism by facilitating the transport of long-chain fatty acids into the mitochondria for β-oxidation. It is a critical ingredient for manufacturers in the pharmaceutical, nutraceutical, and functional food and beverage industries, where it is used to support energy production and metabolic health.

Application

• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) targeting metabolic disorders and cardiovascular health.
• Dietary Supplements & Nutraceuticals: A key component in capsules, tablets, and powders aimed at enhancing physical performance, supporting weight management, and promoting overall energy metabolism.
• Functional Food & Beverage Fortification: Incorporated into energy drinks, sports nutrition products, and health-focused foods to provide metabolic benefits.
• Animal Feed Additives: Used in poultry, swine, and aquaculture feed formulations to improve growth performance, feed efficiency, and meat quality.
• Cosmetic & Personal Care: Employed in skincare formulations for its potential antioxidant properties and role in cellular energy, helping to revitalize the skin.
• Research & Development: Serves as a standard or reagent in biochemical research, clinical diagnostics, and metabolic studies.

Quality Control

Our Dl-Carnitine is produced under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and nutraceutical applications. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles. Specifications can be aligned with various pharmacopoeial standards, including USP and EP, upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
