Manufacturing Quality Control of 3-Pyridylacetic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity | High-Performance Liquid Chromatography (HPLC) | Using a reverse-phase C18 column with phosphate buffer-organic solvent as the mobile phase, and a UV detector (e.g., 254 nm) for quantitative analysis of the main component purity. Suitable for samples with content ≥98%. |
| Related Substances/Impurities | HPLC (Gradient Elution) | Separating the main peak from potential impurity peaks using a gradient elution program, calculating the content of each impurity by area normalization or external standard method, complying with ICH Q3A guidelines. |
| Dry Loss | Drying Method (Pharmacopoeia General Method) | Dry the sample at 105°C until constant weight, calculate the percentage of mass loss to evaluate moisture and volatile substance content. |
| Melting Point | Capillary Melting Point Determination | Determine the melting temperature range using a digital melting point apparatus, assess crystalline purity and polymorphic consistency, typical melting point range is about 136–139°C. |
| pH Value | pH Meter Measurement | Prepare a certain concentration aqueous solution (e.g., 1% w/v), calibrate the pH meter and directly measure, controlling the acid-base environment affecting stability. |
| Residual Solvents | Gas Chromatography (GC-FID/HS-GC) | Use headspace sampling or direct injection, separate with capillary columns, quantify residual solvents such as methanol, ethanol, and ethyl acetate using FID detector, complying with ICH Q3C standards. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | Determine the total amount of heavy metals such as lead, cadmium, mercury, and arsenic after digestion treatment, ensuring compliance with pharmacopoeia or customer limits (e.g., ≤10 ppm). |
| Moisture Content | Karl Fischer Titration | Accurately determine trace moisture content using volumetric or coulometric Karl Fischer titrator, especially suitable for hygroscopic compounds. |
| Appearance | Visual Inspection | Observe the color (should be white to off-white crystalline powder), odor, presence of foreign matter or clumping, to preliminarily judge the physical state of the sample. |
| UV Absorption Characteristics | UV-Visible Spectrophotometry | Determine absorbance at specific wavelengths (e.g., 254 nm) to verify structural features or for rapid semi-quantitative analysis. |
