| Pharmaceutical Intermediates | Production of anti-tuberculosis drugs | Bromination, amination, condensation, and related reactions |
| Agrochemical Intermediates | Synthesis of insecticides | Acylation, esterification, condensation, and related reactions |
Manufacturing Quality Control of Pyrazinoic acid hydrazide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~240 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV or UPLC-UV | Separation and quantification of structurally related impurities (e.g., pyrazine-2-carboxylic acid, hydrazine, residual solvents) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, ethanol, DMF) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration based on the stoichiometric reaction of iodine with water in anhydrous pyridine–methanol medium. |
| Heavy Metals | ICP-MS or AAS | Quantification of toxic elements (e.g., Pb, Cd, Hg, As) after microwave-assisted acid digestion; ICP-MS offers multi-element trace detection. |
| Chloride Impurity | Ion Chromatography (IC) or Potentiometric Titration | Separation and quantification of chloride ions via suppressed conductivity detection (IC), or direct titration with silver nitrate. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Appearance and Color | Visual Inspection & Hazen/APHA Color Scale | Subjective assessment of physical state (white to off-white crystalline powder) and color intensity against platinum-cobalt standards. |
| Loss on Drying (LOD) | Gravimetric Analysis (105 °C, 2 h) | Measurement of mass loss after controlled heating under specified conditions to assess volatile content including moisture and residual solvents. |
| pH of Aqueous Solution | pH Meter (1% w/v aqueous suspension) | Electrochemical measurement of hydrogen ion activity in a standardized suspension to assess acidic/basic degradation products. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light to confirm chiral purity (though compound is achiral, detects chiral contaminants or degradation). |
