Manufacturing Quality Control of 4'-Hydroxyacetophenone
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical state of the sample under natural or standard lighting to determine if it is a white to off-white crystalline powder, checking for impurities or discoloration. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (typically at 245–280 nm wavelength), employing methanol-water or acetonitrile-water as the mobile phase. Quantify the main component using external or internal standard methods; purity is typically required to be ≥99.0%. |
| Melting Point | Melting Point Determination (Capillary Method) | Determine the melting temperature using a melting point apparatus or capillary method. The melting point of p-Hydroxyacetophenone is typically 109–112°C, used to assess purity and identity. |
| Moisture Content | Karl Fischer Titration | Use Karl Fischer reagent to titrate water content in the sample; suitable for trace moisture analysis. Moisture content is generally controlled to ≤0.5%. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Detect potential impurities such as synthesis intermediates, by-products, or degradation products (e.g., phenolic compounds, acetylation by-products) using HPLC. Typically, individual impurity ≤0.1% and total impurities ≤0.5%. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Colorimetric Method | After sample digestion, determine residual heavy metals such as lead, cadmium, and mercury using atomic absorption spectroscopy. Limits generally comply with pharmacopoeial requirements (e.g., ≤20 ppm). |
| Residual Solvents | Gas Chromatography (GC) | Detect organic solvents possibly remaining from manufacturing (e.g., methanol, ethanol, acetone, toluene) using headspace GC with FID detection, in compliance with ICH Q3C guidelines. |
| Sulfated Ash / Residue on Ignition | Residue on Ignition Test | Weigh the residue after high-temperature ignition of the sample to evaluate inorganic impurity content. Typically required to be ≤0.1%. |
| pH Value (Solution) | pH Meter Method | Measure the pH of a defined concentration aqueous solution of p-Hydroxyacetophenone (e.g., 1% w/v) using a pH meter to assess acidity or alkalinity. Generally weakly acidic with pH around 5.0–7.0. |
| Infrared Identification (IR) | Fourier Transform Infrared Spectroscopy (FT-IR) | Record infrared spectrum using KBr pellet or ATR method and compare with reference spectrum to confirm consistency of characteristic molecular absorption peaks. |
