Industrial Applications of DL-CYSTEINE HYDROCHLORIDE MONOHYDRATE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate in the synthesis of antibiotics (e.g., cephalosporins) | Chiral resolution or asymmetric synthesis for preparing β-lactam antibiotic side chains |
| Pharmaceuticals | Chelating agent for treating heavy metal poisoning (as an L-cysteine precursor) | Orally administered, then deprotected and metabolized in vivo to active L-cysteine, which participates in metal chelation |
| Food | Dough conditioner (improving gluten structure and extensibility) | Added to flour; thiol groups reduce disulfide bonds to modulate dough rheological properties |
| Cosmetics | Reducing agent in hair care products (e.g., permanent wave solutions) | Releases thiol groups under alkaline conditions to cleave keratin disulfide bonds in hair, enabling curl formation and shaping |
| Animal Feed | Nutritional additive for livestock and poultry (supplying sulfur-containing amino acids) | Co-supplemented with methionine in compound feeds to enhance protein utilization and growth performance |
Manufacturing Quality Control of DL-CYSTEINE HYDROCHLORIDE MONOHYDRATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Homocysteine Hydrochloride) | Acid-Base Titration | Quantification based on neutralization of HCl salt with standardized NaOH solution using potentiometric or indicator endpoint detection. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using reversed-phase chromatography with UV detection at 205-220 nm. |
| Residual Solvents | GC-FID | Identification and quantification of organic solvents (e.g., methanol, acetone, ethyl acetate) using flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric determination of water based on iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element trace metal quantification using inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Chloride Content | Potentiometric Titration | Determination of chloride ions by titration with silver nitrate using silver/silver chloride electrode for endpoint detection. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light induced by chiral molecules in solution at specified concentration and wavelength (589 nm). |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity using calibrated glass electrode in a defined aqueous solution. |
| Residue on Ignition | Gravimetric Analysis | Quantification of inorganic ash content after high-temperature incineration (500-600 C) followed by weighing of residual material. |
| Microbial Limits | Membrane Filtration / Plate Count | Enumeration of aerobic microorganisms and detection of specified pathogens using culture-based methods per pharmacopoeial guidelines. |
| Particle Size Distribution | Laser Diffraction | Size analysis of solid particles in suspension via scattering pattern measurement and Mie theory calculation. |
| Appearance (Color and Clarity) | Visual Inspection | Assessment against standard references for color (e.g., APHA scale) and clarity (absence of visible particulates or haze) in solution. |
