Manufacturing Quality Control of 1-Amino-7-naphthol
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, state, and presence of impurities with the naked eye. 1-Amino-7-naphthol is typically a white to light yellow crystalline powder. |
| Melting Point | Capillary Melting Point Determination | Fill the sample into a capillary tube and heat it in a melting point apparatus to record the initial and final melting temperatures, which are used to assess purity (pure compound has a melting point of approximately 168–172 °C). |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 column with methanol-water or acetonitrile-water as the mobile phase. Detect using a UV detector (e.g., 254 nm) and quantify the main component by external standard or internal standard method. |
| Loss on Drying | Oven-Drying Weight Loss Method | Dry the sample at a specified temperature (e.g., 105 °C) until constant weight is achieved, then calculate the percentage of mass loss to evaluate moisture and volatile content. |
| Residue on Ignition | High-Temperature Ashing Method | Char the sample and ignite it in a high-temperature furnace (typically 700–800 °C), then weigh the remaining inorganic material to reflect the total amount of inorganic impurities. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Similar conditions to content determination are used. Detect and control organic impurities (such as unreacted raw materials and byproducts) using normalization of peak areas or the main component self-comparison method with correction factors. |
| pH Value | pH Meter Method | Prepare a solution of defined concentration (e.g., 1%) and measure its acidity or alkalinity using a calibrated pH meter to assess product stability and potential acid-base impurities. |
| Heavy Metals | Thioglycolic Acid Method (or Atomic Absorption Spectroscopy) | Conduct according to pharmacopoeia guidelines. Determine the total amount of heavy metals such as lead, cadmium, mercury, and arsenic via colorimetry or instrumental analysis to ensure compliance with safety limits. |
