Industrial Applications of DL-Lysine monohydrochloride
| Industry | Application | Process |
|---|---|---|
| Animal Feed Industry | Animal feed additive to supplement essential amino acid lysine, promoting livestock and poultry growth and improving feed conversion efficiency | Produced via fermentation and added to compound feeds or premixes in hydrochloride salt form |
| Food Industry | Nutritional fortificant for lysine enrichment in cereal-based foods, infant formula, and other specialized nutrition products | Incorporated directly into raw materials or finished products during food processing, within national regulatory limits |
| Pharmaceutical Industry | Used in the formulation of amino acid infusions, nutritional supplements, and treatments for certain metabolic disorders | Employed as an active pharmaceutical ingredient (API) in compounded amino acid injection formulations or processed into oral dosage forms |
| Cosmetics Industry | Humectant and skin-conditioning agent in skincare products | Incorporated into emulsions, creams, and similar products to enhance skin feel through its hydrophilicity and biocompatibility |
| Biotechnology | Component of cell culture media to support growth of microorganisms or mammalian cells | Dissolved in sterile water or buffer solution and added to basal culture media to maintain normal cellular metabolism |
Manufacturing Quality Control of DL-Lysine monohydrochloride
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Identification Test | Chemical Color Reaction, Infrared Spectroscopy (IR) | The indole-3-acetic acid reaction produces a purple color to confirm the amino acid structure; or infrared spectroscopy is used to compare with standard spectra for qualitative analysis. |
| Content Determination | Non-aqueous Titration, High-Performance Liquid Chromatography (HPLC) | Non-aqueous titration: in an acetic acid medium, using perchloric acid standard solution for titration; HPLC method: separation on a reverse-phase column and quantification by UV detection. |
| Optical Rotation | Polarimetry | The sample is prepared as a solution of a certain concentration, and its optical rotation is measured using a polarimeter under sodium light, then the specific rotation is calculated. |
| Dry Loss | Thermogravimetric Analysis (Constant Pressure Drying Method) | The sample is dried at 105°C until constant weight is reached. The moisture content is calculated based on the weight loss, typically drying for 2–4 hours. |
| Residue on Ignition (Furnace Residue) | Sulfuric Acid Treatment Followed by High-Temperature Incineration | Sulfuric acid is added, and the sample is incinerated at 500–600°C until constant weight is achieved to determine the residual inorganic impurities. |
| Chlorides | Argentometric Titration (Sodium Chloride Standard Solution) | In nitric acid medium, silver nitrate is added, forming a turbid silver chloride solution, which is compared with a standard chloride solution for quantitative determination. |
| Sulfates | BaCl₂ Turbidimetry | In hydrochloric acid medium, barium chloride is added, forming a turbid barium sulfate solution, which is compared with a standard sulfate solution for determination. |
| Heavy Metals | Thioacetamide Method (Chinese Pharmacopoeia Method) | In weakly acidic conditions, thioacetamide decomposes to produce hydrogen sulfide, which reacts with heavy metal ions to form colored precipitates, and the concentration is determined by colorimetry. |
| pH Value | pH Meter Measurement | The sample is prepared as a solution of a certain concentration (e.g., 5%), and the pH value is directly measured using a calibrated pH meter. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Reverse-phase HPLC is used with gradient or isocratic elution to detect other amino acids or degradation impurities, and the area of each impurity peak is calculated. |
| Microbial Limits | Microbial Limits Testing | Aerobic microbial count, mold and yeast count, and control organisms (e.g., Escherichia coli) are tested according to pharmacopoeia requirements. |
