Manufacturing Quality Control of 4-AMINO-5-BROMO-2-CHLOROPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., dehalogenated, hydrolyzed, or isomeric by-products) via gradient HPLC separation and UV response. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., DMF, THF, methanol) using capillary GC with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pd, Ni, Fe, Cu) after acid digestion using inductively coupled plasma mass spectrometry for sub-ppt sensitivity. |
| Chloride Content | Ion Chromatography | Quantifies inorganic chloride ions (from hydrolysis or salt residues) using suppressed conductivity detection after anion exchange separation. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled ashing at 700-800 C, expressed as percentage of initial sample mass. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via comparison to reference material. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against established specifications under standardized lighting. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume of freely settled and tapped powder using a calibrated graduated cylinder and precision balance. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dry powder using Mie scattering theory applied to laser light diffraction patterns. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral impurities or degradation products in solution, though compound is achiral; used to detect enantiomeric contaminants. |
