Manufacturing Quality Control of BENZYL PHENYL CARBONATE 97
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Appearance | Visual Inspection | Assessment of physical state and color by observing sample in a clear glass container under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on iodine reaction with water in anhydrous methanol/pyridine medium. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight and measuring non-volatile inorganic residue as percentage of original mass. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and plasma excitation. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally related impurities using diode-array detection and retention time matching. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acids with standardized KOH solution using phenolphthalein indicator. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample with sulfuric acid followed by high-temperature ashing and weighing of residual sulfate salts. |
| Solvent Residues | GC-FID | Detection and quantification of residual solvents (e.g., toluene, ethanol) using gas chromatography with flame ionization detection. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and identity. |
