Description

Dl-Acetylmethionine Calcium Salt CAS NO 3409-56-1 is a chemically modified derivative of the essential amino acid methionine, stabilized as a calcium salt. This compound is valued for its enhanced stability and bioavailability compared to the free amino acid, making it a crucial ingredient in specialized nutritional and pharmaceutical formulations. It is primarily sought by manufacturers in the animal feed, nutraceutical, and pharmaceutical industries for its role in supporting metabolic functions and as a source of organic calcium and sulfur.

Application

• Animal Feed Additive: Used as a protected methionine source in poultry, swine, and aquaculture feed to improve growth performance, feathering, and overall animal health.
• Dietary Supplements: Incorporated into human and veterinary nutritional supplements to support liver function, antioxidant status, and as a bioavailable source of sulfur-containing amino acids.
• Pharmaceutical Intermediates: Serves as a key building block or precursor in the synthesis of more complex pharmaceutical agents and peptide-based drugs.
• Clinical Nutrition: Utilized in enteral and parenteral nutrition formulas for patients with specific metabolic needs or amino acid deficiencies.
• Cosmetic Ingredients: Found in high-end skincare formulations for its potential antioxidant properties and role in supporting skin protein synthesis.
• Research & Development: Employed in biochemical research, cell culture media, and as a standard in analytical laboratories.

Quality Control

Our Dl-Acetylmethionine Calcium Salt is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets specifications for identity, purity, and heavy metal content. While we offer standard commercial and feed grades, production can be aligned with GMP principles for critical applications. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
