Manufacturing Quality Control of Methyl 2-(chlorosulfonyl)benzoate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 230 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3A. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, dichloromethane) against calibrated standards. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; measures total water content including bound and free moisture. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on an anion-exchange column with conductivity detection; quantified against sodium chloride calibration standards. |
| Sulfate Impurity | Ion Chromatography | Anion-exchange separation followed by conductivity detection; sulfate quantified relative to potassium sulfate standards. |
| Heavy Metals | ICP-OES | Digestion followed by multi-element detection via inductively coupled plasma optical emission spectroscopy; total metals reported as Pb equivalent per USP <231>. |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator; measures free acid groups hydrolyzable under mild conditions. |
| Residue on Ignition | Gravimetric Analysis | High-temperature ashing of sample followed by weighing of inorganic residue; indicates non-volatile inorganic contaminants. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary method per USP <741>. |
| Appearance | Visual Inspection | Assessment of color and physical state (crystalline powder) against established reference standards under controlled lighting. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light by chiral components in solution; used to confirm stereochemical integrity if applicable. |
