L-threonine

L-Threonine (CAS 72-19-5), commonly referred to by its three-letter code Thr, is an essential amino acid used as a nutritional supplement and feed additive across food, pharmaceutical, and agricultural markets.

It supports protein synthesis in both human and animal nutrition, making it a high-volume ingredient in balanced diet formulations. In animal feed, it is added to swine and poultry diets to optimize protein utilization.

This amino acid helps reduce crude protein content, lowering feed costs without compromising growth performance. Food and beverage manufacturers incorporate it as a flavoring agent under FEMA 4710.

In these applications, it contributes to taste profile development in processed products. Pharmaceutical and nutraceutical producers use it in amino acid infusion solutions, dietary supplements, and clinical nutrition formulas.

These formulas often target protein deficiency. Biotechnology applications include use as a fermentation nutrient and building block in peptide synthesis for research and production-scale processes.

The product is supplied as a white crystalline powder in feed-grade and food-grade specifications. Feed-grade material typically meets a minimum 98.5% purity standard aligned with major pharmacopeial benchmarks.

Food and pharmaceutical applications are served by USP, FCC, and AJI92 grades. Bulk quantities are standard for feed and industrial buyers, with smaller packaging available for specialty nutrition use.
