Manufacturing Quality Control of 4-BROMOPHENYL ISOTHIOCYANATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities by HPLC-UV; identification and quantification against reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., acetone, toluene, methanol) based on calibrated response. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against chloride standard calibration. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to assess inorganic ash content. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of neat sample under controlled white light against defined specifications. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light through a solution to detect chiral impurities or enantiomeric excess. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine D10, D50, D90 values per ISO 13320. |
