Manufacturing Quality Control of 3-Amino-pyridin-2-ol hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and peak area normalization. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., methanol, acetone, ethyl acetate) using gas chromatography with flame ionization detection. |
| Loss on Drying | Gravimetric (105 C) | Measurement of mass loss after drying at 105 C for 2 hours under atmospheric pressure, indicating volatile content including water and residual solvents. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine total water content based on stoichiometric reaction. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode to determine chloride ion concentration based on precipitation endpoint. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in a 1% w/v aqueous suspension using calibrated pH meter with glass electrode. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, reflecting purity and identity via thermal behavior. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles or discoloration against defined standards under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in dry powder form using light scattering principles and Mie theory-based calculation. |
| Microbial Limits | Membrane Filtration + Culture | Enumeration of aerobic mesophilic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) by filtration and selective agar culture. |
