Manufacturing Quality Control of 2-Nitro-4-methylsulfonylbenzoic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance and Characteristics | Visual Inspection / Microscopic Observation | Observe the color, crystal form, and particle condition of the sample. It should be a white to off-white crystalline powder. |
| Identification | Infrared Spectroscopy (IR) Proton Nuclear Magnetic Resonance (¹H NMR) |
IR: Compare characteristic absorption peaks of functional groups (e.g., carboxylic acid O-H, nitro NO₂, sulfone S=O); ¹H NMR: Confirm aromatic protons, methyl signals, and substitution pattern consistent with the structure. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 chromatographic column, with an appropriate mobile phase (e.g., methanol/water + buffer salt or acetonitrile/water system) for separation, and a UV detector (typically at 254 nm or 280 nm) for quantification of the main component. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Same as content determination conditions or use a gradient elution program to separate and detect process impurities, degradation products, etc. Calculate the impurity content using area normalization or with correction factors. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Pressure Drying Method | Dry at a specified temperature (e.g., 105°C) until constant weight is achieved, and measure the percentage loss of water and volatile substances. |
| Melting Point | Melting Point Apparatus | Determine using capillary method or digital melting point apparatus. Confirm the melting range meets the standard (typical range about 210–215°C, specific value depends on literature). |
| pH Value (Solution) | pH Meter Measurement | Prepare a solution of certain concentration (e.g., 1% w/v) in water, and measure its acidity or alkalinity using a calibrated pH meter (expected to be acidic due to the presence of carboxylic acid). |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection, with polar or non-polar capillary columns and FID detector, to detect residual organic solvents used during synthesis (e.g., toluene, dichloromethane, DMF, etc.). |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) |
Dissolve the sample and determine the total amounts of heavy metals such as lead, arsenic, cadmium, and mercury, ensuring they meet pharmacopoeia or regulatory limit requirements. |
| Sulfate Ash / Ignition Residue | High-Temperature Combustion Method | Ignite the sample at a high temperature (usually 700–800°C), weigh the residue, and evaluate the content of inorganic impurities. |
