Manufacturing Quality Control of 1,3-Diphenylguanidine
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | The sample is placed on a white background and observed under natural light or standard illumination to assess its color, physical state, and presence of impurities. Typically appears as a white to pale yellow crystalline powder. |
| Melting Point | Capillary Melting Point Determination | The melting temperature range of the sample is determined using a melting point apparatus or capillary method. The melting point of diphenylguanidine generally ranges from 144–148°C and is used to assess purity. |
| Content (Active Ingredient) | Non-aqueous Titration | Titration with perchloric acid standard solution using glacial acetic acid as the solvent; the endpoint is determined by potentiometry or an indicator (e.g., crystal violet). Suitable for determining basic substances with high accuracy. |
| Drying Loss | Oven Drying Method | The sample is dried at a specified temperature (e.g., 105°C) until constant weight is achieved. The weight loss is used to calculate moisture and volatile content, reflecting product stability and storage performance. |
| Residue on Ignition (Ash) | Gravimetric Method | The sample is incinerated at high temperature, and the residual inorganic matter is weighed to calculate the percentage of residue. Typically required to be ≤0.5%. |
| Heavy Metals | Sulfide Colorimetric Method (e.g., Lead) | After sample treatment, reaction with sodium sulfide produces colored sulfides; colorimetry is used to determine heavy metal content (expressed as Pb). Limit is generally ≤10 ppm. |
| Chlorides | Silver Nitrate Turbidimetric Method | After dissolving the sample, silver nitrate is added to form a turbidity of silver chloride, which is compared visually or instrumentally against a standard series to control inorganic chloride impurities. |
| Sulfates | Turbidimetric Method | In acidic conditions, reaction with barium chloride forms barium sulfate precipitate; turbidity is measured to determine sulfate content. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Reverse-phase HPLC (e.g., C18 column) with UV detection (approximately 254 nm) is used for gradient or isocratic elution to separate and detect organic impurities in diphenylguanidine, evaluating purity and by-products. |
