Industrial Applications of 4-METHYLTHIAZOLE-2-THIOL
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate for antibacterial agents, used in the synthesis of cephalosporin antibiotics (e.g., cefetamet) | Condensed with the β-lactam ring side chain, followed by oxidation and salt formation to produce the final product |
| Agrochemicals | Intermediate for fungicides and plant growth regulators | Participates in heterocycle construction reactions to synthesize thiazole-based agricultural active ingredients (e.g., thiabendazole derivatives) |
| Materials Science | Precursor for dopants in electron-transport layers of organic light-emitting diode (OLED) devices | Forms metal complexes via coordination with metal ions (e.g., Zn²⁺, Cu²⁺), enabling functional thin-film fabrication by vacuum deposition or solution processing |
Manufacturing Quality Control of 4-METHYLTHIAZOLE-2-THIOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~240–260 nm, comparing peak area against a certified reference standard. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of residual metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on element-specific atomic emission intensities. |
| Residual Solvents (e.g., methanol, toluene) | GC-FID | Separation and quantification of volatile organic solvents using capillary GC with flame ionization detection, calibrated with standard solutions. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary apparatus per USP <741>. |
| Sulfur Content | Oxidative Combustion followed by IC | Complete combustion to sulfate, followed by ion chromatographic quantification of SO₄²⁻ anion. |
| Related Substances (Impurities) | HPLC-UV (with gradient elution) | Identification and quantification of structurally related impurities (e.g., 4-methylthiazole, disulfide dimer) using validated stability-indicating HPLC method. |
| pH of Aqueous Suspension (1% w/v) | pH Meter Measurement | Measurement of pH in a standardized aqueous suspension using calibrated pH electrode per EP 2.2.3. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determination of inorganic residue after controlled high-temperature ashing (700–800 °C) and weighing. |
| Odor and Appearance | Visual and Olfactory Inspection | Qualitative assessment of physical state, color (off-white to pale yellow crystals), and characteristic thiol odor under controlled lighting and ventilation. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size via light scattering pattern generated by dispersed particles in air stream. |
| Thiolic Sulfhydryl Content | Iodometric Titration | Quantitative oxidation of –SH group by standardized iodine solution; endpoint detected by starch indicator. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation and quantification of Cl⁻ anion after aqueous extraction and filtration, using suppressed conductivity detection. |
| Specific Optical Rotation | [α]D | Measurement of rotation of plane-polarized light at 589 nm using sodium D-line, reported as degrees per dm·g/mL in specified solvent (e.g., ethanol). |
