Manufacturing Quality Control of 4-Cyano-3-methylBenzoic acid methyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220-254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification via retention time matching and threshold-based reporting per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection for quantitative analysis of common solvents (e.g., methanol, toluene, DMF) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element detection and quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and dilution. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in sample solution prepared by dissolution and filtration. |
| Acid Value | Acid-Base Titration | Neutralization of free acid groups with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint detection. |
| 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 against established reference standards under controlled lighting conditions. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (600-800 C) to quantify inorganic non-volatile impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using light scattering principles to determine D10, D50, D90 values. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution to confirm chiral integrity and absence of racemization. |
