Manufacturing Quality Control of Bis(pinacolato)diboron
| Test Item | Common Test Methods | Method Summary |
|---|---|---|
| Appearance | Visual Inspection / Colorimetric Method | Visually examine the sample's color and physical state (typically white to off-white crystalline powder). Compare with standard color solutions if necessary to determine compliance with specifications. |
| Identification | Infrared Spectroscopy (IR) Proton Nuclear Magnetic Resonance (¹H NMR) |
IR: Record the infrared absorption spectrum of the sample and compare characteristic absorption peaks (e.g., B–O, C–O functional groups) with those of a reference standard or pharmacopoeial spectrum. ¹H NMR: Confirm molecular structure features through chemical shifts and integration areas, particularly the methyl signals of the pinacol group (~1.2 ppm). |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with methanol-water or acetonitrile-water as the mobile phase. Detect at UV wavelength of 200–220 nm and quantify the main component using external or internal standard method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Similar conditions as assay, but with optimized gradient elution to separate potential impurities (e.g., unreacted starting materials, hydrolysis products, oxidation by-products). Impurity levels are calculated using area normalization or a main component self-dilution method with correction factors. |
| Water Content | Karl Fischer Titration | Quantitatively determine water content based on the reaction of iodine with sulfur dioxide in the presence of pyridine/imidazole. Water is measured via coulometric or volumetric titration to ensure product stability. |
| Residual Solvents | Gas Chromatography (GC) | Headspace or direct injection into a GC system equipped with polar or non-polar capillary columns and an FID detector to determine residual organic solvents (e.g., toluene, dichloromethane, ethanol) from synthesis or purification processes. |
| Melting Point | Capillary Melting Point Determination | Pack sample into a capillary tube and heat gradually in a melting point apparatus. Record the temperature range from initial melting to complete liquefaction, and compare with literature values (approx. 135–140 °C) for purity assessment. |
| Boron Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) or Titration |
ICP-OES: Digest the sample and measure boron element content to verify active ingredient proportion. Titration: Indirect determination of boron content via acid-base or complexometric titration (less common, lower accuracy). |
