Manufacturing Quality Control of 3,5-Pyridinedicarboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies 3,5-pyridinedicarboxylic acid by titration with standardized NaOH using phenolphthalein or potentiometric endpoint detection. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric reaction between water and iodine in a pyridine-methanol solvent system. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by ignition at 700-800 C and weighing the residual ash. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) after acid digestion by measuring element-specific emission intensities. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using an anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under controlled pH and temperature, followed by filtration and weighing. |
| Related Substances | HPLC-UV | Separates and detects structurally related impurities (e.g., mono-acids, esters, isomers) using reversed-phase C18 column and UV detection at 254 nm. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP/Ph. Eur. guidelines. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity in a 1% w/v aqueous suspension using calibrated pH electrode and buffer standards. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Identifies and quantifies residual solvents (e.g., methanol, acetone, DMF) using capillary column and flame ionization detection. |
| Iron Content | Atomic Absorption Spectroscopy (AAS) | Quantifies iron after sample digestion by measuring absorption of characteristic wavelength light (248.3 nm) in acetylene-air flame. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against standard white background under controlled lighting per ICH Q5A. |
