Manufacturing Quality Control of 3-(METHYLTHIO)PHENYLBORONIC ACID PINACOLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual boronic acid, hydrolysis products) via gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generated electrochemically in pyridine-methanol medium. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residual Boric Acid | Acid-Base Titration | Titrates liberated boric acid (after ester hydrolysis) with mannitol-enhanced NaOH solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or phase separation against standard reference under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature (600-800 C) incineration and weighing of residue. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions released upon sample decomposition using suppressed conductivity detection. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of a known mass in a graduated cylinder per USP <616>. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder using light scattering pattern analysis with a validated laser diffraction instrument. |
