Manufacturing Quality Control of 2-Amino-6-nitrobenzoic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance and Physical Properties | Visual Inspection + Physical Property Measurement | Observe the sample's color (usually a yellow to orange-yellow crystalline powder), crystal form, solubility (slightly soluble in water, easily soluble in ethanol, ether, and alkaline solutions), etc. |
| Melting Point | Capillary Melting Point Apparatus Method | Determined according to the Chinese Pharmacopoeia or USP method, the melting point of 2-aminobenzoic acid is approximately 268–272 °C, used for preliminary purity assessment. |
| Content Determination (Main Component) | High-Performance Liquid Chromatography (HPLC) | Use a C18 chromatographic column, with a mobile phase of methanol-water (with 0.1% formic acid or phosphate buffer), detected by ultraviolet detector (wavelength 254–280 nm), external standard method for quantification, high accuracy, suitable for quantitative analysis. |
| Content Determination (Main Component) | UV-Vis Spectrophotometry | Determine absorbance at maximum absorption wavelength (approximately 270–280 nm), calculate content through standard curve, suitable for rapid screening, but prone to interference from impurities. |
| Impurity Analysis | High-Performance Liquid Chromatography (HPLC) | Use gradient elution or isocratic elution, detect possible impurities such as 2-nitrobenzoic acid, 2,6-dinitrobenzoic acid, unreacted raw materials, etc., calculate total impurities and individual impurity limits. |
| Moisture Content | Karl Fischer Titration | Accurately determine the trace moisture content in the sample, control the impact of moisture on stability, typically requiring moisture ≤1.0%. |
| Inorganic Impurities such as Chlorides and Sulfates | Turbidimetry / Ion Chromatography | Process the sample according to pharmacopoeia methods, determine chloride or sulfate ion content by turbidimetry, or perform quantitative analysis using ion chromatography. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | Determine the content of heavy metals such as lead, cadmium, mercury, and arsenic after ashing or digestion of the sample, complying with ICH Q3D or pharmacopoeia limits (e.g., ≤20 ppm). |
| Particle Size Distribution (if applicable) | Laser Diffraction or Microscopy | For powder formulation raw materials, measure the particle size distribution to ensure process consistency, especially affecting dissolution and homogeneity in formulations. |
| Solvent Residues | Gas Chromatography (GC) | Detect residual organic solvents (such as methanol, ethanol, acetone, ethyl acetate) during production, controlled within limits according to ICH Q3C standards. |
| pH Value (in Aqueous Solution) | pH Meter Method | Prepare a saturated aqueous solution (or appropriate concentration), measure pH with a calibrated pH meter. The aqueous solution of 2-aminobenzoic acid is weakly acidic (pH ≈ 4–6), reflecting the state of acidic groups. |
| Identification Test | Fourier Transform Infrared Spectroscopy (FT-IR) | Compare characteristic absorption peaks with standard spectra (e.g., carboxyl group C=O stretching vibration ~1680 cm⁻¹, amino N-H ~3400 cm⁻¹, nitro NO₂ ~1530, 1350 cm⁻¹) to confirm the structure. |
| Identification Test | Thin-Layer Chromatography (TLC) | Use silica gel plates, develop with an eluent such as ethyl acetate: methanol: glacial acetic acid (8:2:1), visualize with iodine vapor or under UV light, compare Rf values with reference standards. |
