Manufacturing Quality Control of 3-Nitro-4,5-dihydroxybenzaldehyde
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and visible impurities of the sample. This compound is typically a yellow to yellow-brown solid. |
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with UV detection (e.g., 254 nm or set according to maximum absorption wavelength). Qualify via retention time and quantify using peak area normalization or external standard method to assess the purity of the target compound. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Utilize ¹H-NMR and ¹³C-NMR to analyze the compound's structure, confirming chemical shifts of protons/carbons on the aromatic ring and substitution pattern consistent with 3,4-dihydroxy-5-nitrobenzaldehyde. |
| Structural Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) | Detect characteristic absorption peaks of functional groups, such as aldehyde (~1700 cm⁻¹), hydroxyl (~3200–3500 cm⁻¹), and nitro (~1530 and ~1350 cm⁻¹), to verify molecular structure. |
| Molecular Weight Confirmation | Mass Spectrometry (MS, e.g., ESI-MS or EI-MS) | Determine the molecular ion peak ([M+H]+ or M•+), confirming the molecular weight is 183.05 g/mol (C₇H₅NO₅). |
| Moisture Content | Karl Fischer Titration | Quantitatively determine the water content in the sample, suitable for assessing the dryness level and stability of raw materials. |
| Residual Solvents | Gas Chromatography (GC) | If organic solvents (e.g., methanol, ethanol, DMF, etc.) were used during synthesis, GC is employed to detect residual solvent levels, ensuring compliance with pharmacopeial or safety standards. |
| Melting Point | Melting Point Determination (Capillary Method or DSC) | Determine the melting temperature to assess purity and consistency; impurities may cause a lower melting point or broader melting range. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Detect harmful element residues such as lead, mercury, cadmium, and arsenic, ensuring compliance with safety requirements for chemicals or pharmaceutical intermediates. |
| Residue on Ignition | Sulfated Ash Test | Ignite the sample at high temperature and weigh the residue to evaluate the content of inorganic impurities. |
