For B2B procurement managers and product developers in the chemical, pharmaceutical, and food industries, understanding the precise specifications of raw materials is non-negotiable. L-Cysteine, a fundamental amino acid, requires careful consideration of its purity, physical characteristics, and certifications to ensure it meets the exact needs of your application. As a leading manufacturer of L-Cysteine powder (CAS 52-90-4), we are dedicated to providing transparent and detailed product information to facilitate informed purchasing decisions.

Our L-Cysteine powder is manufactured to meet stringent quality standards. The primary specification is its assay, which typically ranges from 98.0% to 101.0%. This high level of purity is critical for applications where precise chemical composition is essential, such as in pharmaceutical synthesis or in the formulation of sensitive nutritional products. We ensure that each batch undergoes rigorous testing to confirm it meets these exacting standards, providing buyers with confidence when they buy L-Cysteine.

The appearance of our L-Cysteine powder is consistently white powder, a visual indicator of its high purity and quality. We also provide key physical and chemical properties relevant to its handling and application. For instance, the loss on drying is typically kept to a maximum of 0.50%, and the residue on ignition is also minimal (≤0.10%), further underscoring the product's quality. Parameters like heavy metals (Pb ≤10 PPM), chloride, arsenic, iron, ammonium, and sulfate are all controlled within strict limits, ensuring compliance with international safety regulations for food and pharmaceutical ingredients.

Certifications are paramount in the B2B procurement landscape. Our L-Cysteine is often supplied with certifications such as ISO9001, Fami-QS, FDA, Halal, HACCP, and GMP, depending on the specific grade and intended market. These certifications serve as external validation of our manufacturing processes and product quality. For buyers seeking a reliable supplier of L-Cysteine in China, these credentials offer assurance of our commitment to excellence and regulatory adherence.

When considering the purchase of L-Cysteine, understanding these technical details is crucial for making an informed choice. We encourage procurement professionals to reach out to us for detailed technical data sheets, Certificates of Analysis (COA) for specific batches, and to discuss your unique requirements. We aim to be more than just a supplier; we strive to be a trusted partner, ensuring you have access to the highest quality L-Cysteine powder at competitive wholesale prices. Secure your supply chain with a manufacturer that prioritizes precision and quality.
