Manufacturing Quality Control of 1H-Pyrazole-4-sulfonamide,1,3-dimethyl-(9CI)
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, form (e.g., white to off-white crystalline powder), and presence of foreign matter or lumps. |
| Identification | Infrared Spectroscopy (IR) | Confirm the consistency of molecular functional groups by comparing the absorption spectrum of the sample with that of a reference standard. |
| High-Performance Liquid Chromatography (HPLC) | Identify the target compound by comparing retention time with that of a reference standard. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Determine the content of the main component using external or internal standard methods, calculating based on peak area; ensure it meets pharmacopoeia or enterprise standards (e.g., ≥98.0%). |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Separate and detect impurity peaks using a gradient elution program, calculate individual impurities and total impurity limits using area normalization or self-reference method. |
| Loss on Drying | Drying Loss Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, and calculate the percentage of mass loss to control moisture and volatile substances. |
| Residue on Ignition | Muffle Furnace Ashing Method | Weigh the residue after incinerating the sample at high temperature (e.g., 600–800°C) to evaluate the content of inorganic impurities (usually ≤0.1%). |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | Determine the total amount of heavy metals such as lead, arsenic, cadmium, and mercury after digestion, ensuring compliance with ICH Q3D or pharmacopoeia limits. |
| Residual Solvents | Gas Chromatography (GC) | Analyze via headspace or direct injection to detect organic solvents potentially remaining from synthesis (e.g., methanol, ethyl acetate), ensuring compliance with ICH Q3C. |
| pH Value | pH Meter Measurement | Determine the acidity or alkalinity by measuring a solution of a certain concentration with a calibrated pH meter, assessing product stability and applicability. |
| Melting Point | Capillary Melting Point Determination | Determine the temperature range from initial melting to complete melting, serving as an indicator of purity and identification (refer to literature values). |
