Industrial Applications of Calcium bis(2-hydroxy-4-(methylthio)butyrate)
| Industry | Application | Process |
|---|---|---|
| Animal Feed Industry | Methionine nutritional additive | Used as a limiting amino acid supplement to support protein synthesis in animals, enhance dietary protein utilization, and reduce feed formulation costs. |
| Animal Feed Industry | Prevention and treatment of feather pecking in poultry | Supplies sulfur-containing amino acids to promote feather growth and keratin synthesis, alleviating abnormal behaviors such as feather pecking and vent pecking caused by methionine deficiency. |
| Livestock Farming | Rumen-protected nutrient supplementation for ruminants | Leverages the slower degradation rate of calcium hydroxymethionine in the rumen; enables targeted release and absorption in the small intestine via rumen protection, thereby improving milk yield and milk protein content. |
| Food Industry | Food nutritional fortificant | Serves as a source of calcium and amino acids for nutritional fortification of specialized food products (subject to applicable food additive regulations). |
| Chemical Synthesis | Pharmaceutical and chemical intermediate | Used in the synthesis of specific pharmaceuticals or as a sulfur- and calcium-containing structural building block in organic synthesis. |
Manufacturing Quality Control of Calcium bis(2-hydroxy-4-(methylthio)butyrate)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Hydroxy Methylthio Butanoic Acid Calcium Salt) | Acid-Base Titration | Quantifies active ingredient by titration with standardized HCl after alkaline hydrolysis and back-titration. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying at 105 C to determine volatile content including moisture and residual solvents. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Simultaneously quantifies trace heavy metals using inductively coupled plasma mass spectrometry for high sensitivity and multi-element detection. |
| Calcium Content | Complexometric Titration (EDTA) | Determines Ca2+ concentration by titration with standardized EDTA solution using Eriochrome Black T indicator. |
| Chloride Impurity | Potentiometric Titration (AgNO3) | Measures chloride ions via argentometric titration with silver nitrate and silver electrode detection. |
| Sulfate Impurity | Gravimetric Analysis (BaSO4) | Precipitates sulfate as barium sulfate and determines content by weighing the dried precipitate. |
| pH of Aqueous Suspension | pH Meter Measurement | Measures hydrogen ion activity in a defined suspension (e.g., 10% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size based on angular variation in laser light scattering intensity from dispersed sample. |
| Bulk Density | Cylindrical Tap Density Tester | Determines mass per unit volume after controlled tapping of a known mass in a standard cylinder. |
| Microbial Contamination (Total Aerobic Count) | Plate Count Agar Method | Quantifies viable aerobic microorganisms by colony formation on nutrient agar after incubation at 30-35 C for 48-72 h. |
| Residual Solvents (Methanol, Ethanol) | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents using capillary column and flame ionization detection. |
| Identification (FTIR Fingerprint) | Fourier Transform Infrared Spectroscopy | Confirms molecular structure by comparing characteristic absorption bands in mid-IR region (4000-400 cm-1) to reference spectrum. |
