Industrial Applications of Phenylhydrazine hydrochloride
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used in the synthesis of the anti-tuberculosis drug isoniazid | Isoniazid is prepared via chemical reaction using phenylhydrazine hydrochloride as the starting material |
| Pharmaceuticals | Serves as a pharmaceutical intermediate in the synthesis of other medicinal products | Participates in multi-step organic synthesis reactions to generate target compounds |
| Analytical Chemistry | Used as an analytical reagent for the detection of aldehydes and ketones | Forms hydrazone derivatives through condensation reactions with aldehydes or ketones, enabling qualitative or quantitative analysis |
| Dye Industry | Used in the synthesis of azo dyes | Azo dyes are prepared via diazotization followed by coupling reactions |
| Pesticides | Serves as a pesticide intermediate in the synthesis of insecticides or herbicides | Target pesticide products are generated via specific chemical reaction pathways |
Manufacturing Quality Control of Phenylhydrazine hydrochloride
| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Assay | Non-aqueous Titration | Titrated with perchloric acid standard solution using glacial acetic acid as solvent. The endpoint is determined potentiometrically or by indicator (e.g., crystal violet), used to determine the content of basic groups in phenylhydrazine hydrochloride. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column and UV detector (around 254 nm). Impurities such as phenylhydrazine and other organic impurities are detected by comparison with reference standards. |
| Loss on Drying | Thermogravimetric Analysis (or Oven Method) | Dried to constant weight at 105°C; the percentage weight loss is measured to assess moisture and volatile impurity content. |
| Sulfated Ash (Residue on Ignition) | Residue on Ignition Test | The sample is ignited at high temperature (500–600°C), and the residue is weighed to evaluate inorganic impurities or sulfate residues. |
| Chlorides | Argentometric Turbidimetry (Silver Nitrate Method) | In nitric acid medium, silver nitrate is added to form turbidity from silver chloride precipitate. The turbidity is compared with a standard chloride solution to control chloride ion impurities. |
| Heavy Metals | Thioacetamide Method (as per Chinese Pharmacopoeia) | In weakly acidic conditions, thioacetamide generates hydrogen sulfide, which reacts with heavy metal ions to form colored precipitates; limit test performed by color comparison. |
| Solution Clarity and Color | Visual Color Comparison/Turbidimetry | The sample is dissolved in water and compared visually with standard color solutions or clarity standards to judge whether the solution is clear and colorless. |
| Melting Point | Capillary Melting Point Determination | The melting point apparatus is used to measure the temperature range from initial melting to complete melting, for identification and purity assessment. |
