Manufacturing Quality Control of 2-CYCLOPENTENYL-4,4,5,5-TETRAMETHYL-1,3,2-DIOXABOROLANE

Detection Item Common Analytical Method Method Overview
Assay (Purity) HPLC-UV Quantitative determination using reverse-phase HPLC with UV detection at 210-230 nm, calibrated against certified reference standard.
Related Substances HPLC-UV Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and relative response factors.
Residual Solvents GC-FID Headspace GC with flame ionization detection to quantify common solvents (e.g., THF, toluene, methanol) per ICH Q3C guidelines.
Water Content Karl Fischer Titration Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction.
Heavy Metals ICP-MS Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using inductively coupled plasma mass spectrometry.
Residue on Ignition Gravimetric Analysis Measurement of non-volatile inorganic residue after high-temperature ashing at 600-750 C and weighing.
Chloride Content Ion Chromatography Separation and quantification of chloride ions using anion-exchange column with conductivity detection.
Acid Value Acid-Base Titration Titration with standardized NaOH solution using phenolphthalein indicator to determine free acidic impurities.
Appearance Visual Inspection Assessment of physical state, color, and clarity against established reference standards under controlled lighting.
Melting Point Capillary Melting Point Apparatus Determination of temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>.
Specific Optical Rotation Polarimetry Measurement of rotation of plane-polarized light at 20 C using sodium D-line (589 nm) to confirm chiral integrity.
Particle Size Distribution Laser Diffraction Analysis of dry or wet dispersed sample using laser scattering to determine D10, D50, D90 values per ISO 13320.
