Manufacturing Quality Control of 5-BROMO-2-PYRAZINECARBOXYLIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode-array detection; relative retention times and UV spectra support structural assignment. |
| Residual Solvents | GC-FID | Quantification of volatile organic solvents (e.g., methanol, ethyl acetate) by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in a controlled anhydrous medium. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, measuring emission intensities of metal-specific wavelengths in inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after anion exchange separation. |
| Sulfated Ash | Gravimetric Analysis | Residue mass after incineration at 700-800 C following sulfuric acid treatment, expressed as percentage of sample weight. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs, observed visually under controlled heating rate. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measurement of mass loss upon heating to 105 C under nitrogen, reflecting volatile content including residual moisture and low-boiling impurities. |
| Optical Rotation | Polarimetry | Measurement of angle of rotation of plane-polarized light induced by chiral centers in solution, reported as specific rotation [alpha]D. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to determine volume-based particle size distribution in dispersed suspension. |
| Microbial Limits | Membrane Filtration | Quantitative recovery and enumeration of aerobic microorganisms by filtration, membrane transfer to culture media, and colony counting after incubation. |
