Manufacturing Quality Control of 4'-Methylbiphenyl-2-carboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV or UPLC-MS | Separation and detection of structurally related impurities (e.g., isomers, des-methyl, oxidation by-products) using gradient elution and UV or mass-selective detection. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., toluene, THF, methanol) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (Pb, Cd, Hg, As) after acid digestion, achieving sub-ppb sensitivity and compliance with ICH Q3D. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with Karl Fischer reagent. |
| Acid Value | Acid-Base Titration (NaOH in ethanol/water) | Neutralization of carboxylic acid groups with standardized sodium hydroxide solution, using phenolphthalein or potentiometric endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Ignition at 700–800 °C followed by gravimetric measurement of inorganic residue after sulfuric acid treatment. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine D10, D50, D90 values based on light scattering principles. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride ions after aqueous extraction and filtration. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line (589 nm) to assess chiral purity (if applicable; typically negligible for this achiral compound, but included for specification consistency). |
