Manufacturing Quality Control of 3-METHOXY-4-METHOXYCARBONYLPHENYLBORONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorbance at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., starting materials, de-boronated or hydrolyzed analogs) via gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, MeOH, EtOAc) using gas chromatography with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration based on iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residual Palladium | ICP-OES | Measures palladium catalyst residue post-synthesis via inductively coupled plasma optical emission spectroscopy after microwave digestion. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid content by titration with standardized NaOH solution using phenolphthalein indicator. |
| Boron Content | ICP-OES | Quantifies total boron after alkaline fusion or acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against established reference standards under controlled lighting. |
| Loss on Drying | Gravimetric Analysis | Measures volatile matter loss by weighing sample before and after drying at specified temperature and vacuum conditions. |
