Manufacturing Quality Control of 2-Hydroxy-1-naphthaldehyde
| Test Item | Common Testing Method | Method Summary |
|---|---|---|
| Appearance and Properties | Visual Inspection / Physical Observation | Observe the sample’s color, state (e.g., white to pale yellow crystalline powder), and odor with the naked eye to determine if it meets standard specifications. |
| Melting Point | Capillary Melting Point Determination | The sample is loaded into a capillary tube and heated in a melting point apparatus or Thiele tube. The initial and final melting temperatures are recorded for purity evaluation and identification purposes. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | A reverse-phase C18 column is used with methanol-water or acetonitrile-water as the mobile phase. A UV detector (typically at 254–330 nm wavelength) is employed for detection, and external standard or internal standard methods are used for quantitative analysis of the main component. |
| Infrared Spectral Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | The sample is prepared as a KBr pellet or using ATR mode. The infrared absorption spectrum is measured and compared to characteristic functional group absorption peaks (e.g., aldehyde C=O ~1680 cm⁻¹, hydroxyl O-H ~3200–3500 cm⁻¹) for structural confirmation. |
| Related Substances (Impurities) | HPLC Method (Gradient Elution) | A gradient elution program is used to separate the main peak from potential impurities (e.g., unreacted raw materials, oxidized or condensed byproducts). The content of each impurity is calculated using area normalization or correction factor methods. |
| Loss on Drying | Oven-Drying Method | The sample is dried at 105°C until constant weight is achieved, and the percentage of mass loss is determined to evaluate water and volatile matter content. |
| Residue on Ignition | High-Temperature Ashing Method | After carbonization, the sample is ashed in a high-temperature furnace at 700–800°C, and the weight of the remaining inorganic residue is measured to control inorganic impurity limits. |
| Heavy Metals | Thioacetamide Colorimetric Method (or ICP-MS) | The sample is processed according to pharmacopoeia methods, followed by addition of a coloring agent for colorimetry, or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is used for precise determination of heavy metal elements such as lead, cadmium, mercury, and arsenic. |
