Manufacturing Quality Control of 4-CHLORO-2-METHYLPHENYLBORONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV or UPLC-MS | Separation and identification of impurities (e.g., starting materials, isomers, hydrolysis/degradation products) via retention time matching and spectral confirmation. |
| Residual Solvents | GC-FID | Quantification of volatile organic solvents (e.g., THF, toluene, methanol) using capillary GC with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous pyridine/methanol medium. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification of trace metals after acid digestion, based on mass-to-charge ratio detection with isotopic resolution and low-ppt sensitivity. |
| Chloride Ion Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on an ion-exchange column and quantitative detection of chloride via suppressed conductivity. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Analysis | Determination of inorganic residue after controlled charring and sulfuric acid treatment followed by high-temperature ashing and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via visual observation of solid-to-liquid phase change under controlled heating rate. |
| Appearance & Color | Visual Inspection / Hazen (APHA) Color Scale | Subjective assessment of physical state and color intensity compared to platinum-cobalt standard solutions. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size based on angular dependence of laser light scattering from a dispersed sample in air or liquid medium. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution at specified wavelength and temperature. |
| Boron Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantification of total boron after microwave-assisted acid digestion via atomic emission at characteristic wavelengths (e.g., 249.773 nm). |
