Manufacturing Quality Control of 16-HEXADECANOLIDE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, state, and transparency of the sample under natural light or standard illumination to determine if it meets the specified characteristics. |
| Purity Analysis | Gas Chromatography (GC) | Use a capillary column with a hydrogen flame ionization detector (FID). Identify components by retention time and quantify using peak area normalization or external standard method. Suitable for volatile samples. |
| High-Performance Liquid Chromatography (HPLC) | If the sample is thermally unstable or non-volatile, use reversed-phase HPLC (e.g., C18 column) with ultraviolet detection (UV, typically at 200–220 nm), quantifying using an external or internal standard method. | |
| Structure Confirmation | Fourier Transform Infrared Spectroscopy (FTIR) | Analyze characteristic functional group absorption peaks, such as the carbonyl (C=O) stretching vibration at approximately 1740 cm⁻¹ and ether (C–O–C) at around 1100 cm⁻¹, to verify the molecular structure. |
| Nuclear Magnetic Resonance Spectroscopy (NMR) | ¹H-NMR and ¹³C-NMR are used to confirm the molecular skeleton structure, especially for cyclic structures and carbonyl positions, providing information on the chemical environment of hydrogen and carbon atoms. | |
| Mass Spectrometry (MS) | Use EI-MS or ESI-MS to determine the molecular ion peak ([M]⁺ or [M+H]⁺), and analyze fragment ions to infer the structure. High-resolution mass spectrometry (HRMS) can determine the molecular formula. | |
| Moisture Content | Karl Fischer Method | This method uses the reaction between iodine and sulfur dioxide in an anhydrous environment to react with water. It precisely measures the moisture content in the sample, with two types: volumetric and coulometric methods. |
| Residual Solvents | Gas Chromatography (GC) | Detect residual organic solvents (such as methanol, ethanol, acetone, dichloromethane, etc.) from the production process according to pharmacopoeia requirements (e.g., Chinese Pharmacopoeia, USP), using headspace-GC-FID. |
| Melting Point/Boiling Point | Melting Point Apparatus or Differential Scanning Calorimetry (DSC) | Determine the melting temperature range of the substance. DSC provides more precise phase transition information, assisting in determining crystallinity and purity. |
| Heavy Metals and Elemental Impurities | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | Detect toxic elements such as lead, arsenic, cadmium, and mercury, ensuring compliance with safety standards for pharmaceuticals or food additives. |
| Microbial Limit | Microbial Limit Test | Conduct tests for total aerobic bacteria count, total mold and yeast count, and control organisms (such as Escherichia coli, Salmonella) according to pharmacopoeia requirements, applicable to pharmaceutical or cosmetic products. |
