Manufacturing Quality Control of (+/-)-2-(6-METHOXY-2-NAPHTHYL)PROPIONIC ACID
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Compare sample spectrum with reference standard; identify functional groups in molecular structure based on characteristic absorption peaks. |
| High-Performance Liquid Chromatography (HPLC) | Identify compounds by comparing retention times with those of reference standards. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use reversed-phase C18 column with UV detector (approximately 230–275 nm), and quantify the main component using external or internal standard method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate degradation products and synthetic intermediates via gradient or isocratic elution, detect and quantify individual impurity levels. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection to detect residual organic solvents (e.g., methanol, ethanol, acetone) from manufacturing processes. |
| Water Content | Karl Fischer Titration | Accurately determine moisture content in samples, suitable for raw material quality control. |
| Polymorphic Analysis | X-Ray Powder Diffraction (XRD) | Analyze crystal structure to confirm presence or absence of polymorphism, ensuring batch-to-batch consistency. |
| Differential Scanning Calorimetry (DSC) | Determine melting behavior and thermal stability to assist in assessing polymorphic purity. | |
| Solution Clarity and Color | Visual Colorimetry or UV-Visible Spectrophotometry | Observe whether the dissolved sample solution is clear and free of noticeable color, or measure absorbance at specific wavelengths. |
| Acid Value / Neutralization Equivalent | Acid-Base Titration | Utilize carboxylic acid group characteristics; titrate with standardized alkaline solution to calculate acid value or neutralization equivalent, verifying purity. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine levels of heavy metals such as lead, cadmium, and mercury to ensure compliance with pharmacopoeial limits. |
| Microbial Limits | Microbial Limit Test | Conduct tests for total aerobic bacteria count, mold and yeast count, and control organisms (e.g., *E. coli*) according to Chinese Pharmacopoeia or USP guidelines. |
