Manufacturing Quality Control of Benzothiophene-3-boronic 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-UV/DAD | Separation and detection of structurally similar impurities (e.g., residual starting materials, deboronated by-products) using gradient HPLC with diode-array detection. |
| Residual Solvents | GC-FID | Quantification of volatile organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection against calibrated standards. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pd, Ni, Fe) after acid digestion, based on mass spectrometric detection of elemental isotopes. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Mass loss upon high-temperature ashing (500–600 °C) followed by weighing of non-volatile inorganic residue. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride anions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection via optical observation of solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized white-light illumination and against reference standards. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed sample using Mie scattering theory to determine volumetric particle size distribution. |
| Boron Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantification of total boron after microwave-assisted acid digestion, based on atomic emission intensity at characteristic wavelength (e.g., 249.773 nm). |
