Manufacturing Quality Control of 785051-54-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV or UPLC-MS | Separation and identification of impurities (e.g., residual starting materials, deboronated by-products, oxidation products) via chromatographic retention and spectral matching. |
| Residual Solvents | GC-FID | Quantification of volatile organic solvents (e.g., THF, toluene, isopropanol) using gas chromatography with flame ionization detection against calibrated standards. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pd, Ni, Fe, Cu) based on atomic mass spectrometry detection after acid digestion and dilution. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water content via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration followed by precise weighing of the residual residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using controlled heating; correlates with crystallinity and presence of impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed powder particle size based on angular scattering intensity of laser light. |
| Chloride Content | Ion Chromatography (IC) | Quantification of chloride ions released during sample hydrolysis, separated on an anion-exchange column and detected conductometrically. |
| Boron Content | ICP-OES | Elemental quantification of total boron via optical emission from excited boron atoms in argon plasma after acid digestion. |
| Optical Rotation | [α]D Measurement | Determination of specific rotation using a polarimeter at 589 nm to assess chiral purity (if applicable to enantiomeric form). |
