For procurement managers and product formulators across various industries, sourcing essential chemical compounds like L-Cystine (CAS 56-89-3) requires a clear understanding of its properties, applications, and the importance of a reliable supplier. L-Cystine, a dimer of cysteine, is a fundamental amino acid recognized for its multifaceted benefits in pharmaceuticals, cosmetics, and animal feed.

Understanding L-Cystine Specifications

Before purchasing, it's crucial for buyers to be aware of the standard specifications for L-Cystine. Typically, it presents as a white crystalline powder. Key quality indicators include its assay, which for high-grade products usually ranges from 98.5% to 101.0%, and its pH, generally between 5.0 and 6.5. These parameters are critical for ensuring that the L-Cystine will perform as expected in your specific applications, whether for intricate pharmaceutical formulations or nutritional supplements. Other specifications like low levels of chloride, sulfate, iron, and heavy metals are also vital for ensuring product safety and efficacy.

Key Applications Driving Demand for L-Cystine

The demand for L-Cystine is driven by its significant roles across several key industries:

  • Pharmaceuticals: It's used in biochemical research, as a component in amino acid infusions, and for its therapeutic properties, such as promoting cellular oxidation-reduction and supporting the immune system.
  • Cosmetics: L-Cystine is valued for its ability to promote wound healing, prevent skin allergies, and contribute to the structural integrity of skin, hair, and nails.
  • Animal Feed: As a nutrient fortifier, it aids in animal development, improves liver and kidney function, and enhances the quality of fur or feathers.

Understanding these diverse applications helps procurement teams identify the precise grade and quantity of L-Cystine required for their operations.
