For procurement professionals and R&D scientists in the chemical, pharmaceutical, and food industries, a thorough understanding of product specifications is vital for successful sourcing. L-Cysteine HCL Anhydrous (CAS 52-89-1) is a compound where precision in quality parameters directly impacts its application efficacy. As a prominent China manufacturer and supplier, we emphasize transparency regarding our product's specifications to build trust and facilitate informed purchasing decisions.

The key specifications for L-Cysteine HCL Anhydrous include its Assay, which typically ranges from 99.0% to 100.5%. This indicates the purity of the product. The pH of its solution is also a critical parameter, usually falling between 1.5 and 2.1, reflecting its acidic nature as a hydrochloride salt. Specific rotation, measured at [α]D20, should fall within the range of +5.5° to +8.9°, confirming its chiral integrity and natural L-configuration.

Impurity levels are another crucial aspect. Limits for Chloride (Cl) are typically 19.8-20.8%, while Ammonium (NH4), Sulfate (SO4), Iron (Fe), Heavy Metals (Pb), and Arsenic are kept to very low ppm levels (e.g., ≤0.02% for NH4, ≤10ppm for Fe and Pb, ≤1ppm for Arsenic). Loss on drying should not exceed 0.5%, and Residue on ignition should be ≤0.10%. For chromatographically sensitive applications, it's important that 'Other amino acids' are not detected.

When you decide to buy L-Cysteine HCL Anhydrous, verifying these specifications with your chosen China supplier is essential.
