Manufacturing Quality Control of 18-(tert-Butoxy)-18-oxooctadecanoic Acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Visually inspect the sample’s color, physical state (e.g., white to off-white powder or crystals), and presence of foreign matter to determine compliance with quality standards. |
| Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Measure the infrared absorption spectrum of the sample and compare characteristic absorption peaks (e.g., ester C=O ~1735 cm⁻¹, carboxylic acid C=O ~1710 cm⁻¹, tert-butyl ester characteristic peaks) with reference spectra to confirm the compound's structure. |
| Identification | Proton Nuclear Magnetic Resonance (¹H NMR) | Measure the ¹H NMR spectrum of the sample in a deuterated solvent and compare chemical shifts, integration areas, and coupling constants to verify structural features (e.g., tert-butyl signal δ≈1.4 ppm, methylene chain signals). |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a mobile phase of methanol/water or acetonitrile/water. Detect with a UV detector (typically 210–220 nm) and calculate the main component content using the external standard method or area normalization method to assess purity. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Under the same conditions as the assay or with a gradient elution program, separate and quantify potential impurities (e.g., unreacted starting materials, hydrolysis product stearic acid, oxidation by-products), and control individual and total impurity limits. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Weight Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, and measure the percentage of mass loss to evaluate the content of moisture and volatile components. |
| Melting Point | Capillary Melting Point Method | Use a melting point apparatus to measure the temperature range from initial melting to complete melting. Compare with literature values (expected ~60–70°C, depending on purity) as an auxiliary indicator of purity. |
| Residual Solvents | Gas Chromatography (GC) | Analyze possible residual organic solvents (e.g., dichloromethane, methanol, diethyl ether) from the synthesis process using headspace or direct injection, polar or non-polar capillary columns, and an FID detector, in compliance with ICH Q3C limits. |
| pH Value (if prepared as a solution) | pH Meter Method | Prepare a solution of the sample in water or a water-organic solvent mixture at a certain concentration and measure the pH using a calibrated pH meter to indirectly reflect the level of free acid or hydrolysis. |
