    Packaging

    L-Threonine is supplied as a crystalline powder and packed in sealed, moisture-resistant packaging to maintain product stability during storage and transportation. Typical formats include multi-layer paper bags with inner polyethylene liners or woven bags with protective lining.

    Packaging is designed for industrial handling and to prevent contamination and moisture uptake. Bulk supply and palletized shipment can be arranged depending on order volume and logistics conditions.

    Storage

    Store in a cool, dry, and well-ventilated environment. Keep containers tightly sealed to avoid moisture absorption and contamination.

    Avoid exposure to direct sunlight and maintain packaging integrity throughout storage and transportation.

    FAQ - Technical & Supply Chain

    • Q:

      What is L-Threonine CAS 72-19-5?

      A: L-Threonine is an essential amino acid with the molecular formula C4H9NO3 and molecular weight 119.12 g/mol. It is normally supplied as a white crystalline powder and is soluble in water, with limited solubility in ethanol.
    • Q:

      What is the main use of L-Threonine?

      A: It is mainly used as a feed additive to balance amino acid profiles in compound feed, premixes, and animal nutrition. L-Threonine is a second limiting amino acid in swine diets and a third limiting amino acid in poultry diets, helping support protein deposition and growth.
    • Q:

      How is L-Threonine produced and what grades are available?

      A: Industrial L-Threonine is commonly produced by microbial fermentation. It is available in feed grade, food grade, and pharmaceutical or biochemical grades; feed-grade material is often specified at 98.5% minimum and supplied under standards such as GB/T 21979-2008.
    • Q:

      What does the L in L-Threonine mean?

      A: The L designation refers to the naturally occurring, biologically active stereoisomer of threonine. L-Threonine is the form used in proteins, animal nutrition, and biochemical systems, whereas DL-threonine contains both enantiomers.
    • Q:

      How should L-Threonine be stored?

      A: Store it in tightly sealed, moisture-resistant containers in a cool, dry, well-ventilated area. Keep the powder away from direct sunlight and excessive humidity, and maintain package integrity during storage and transport.
