Manufacturing Quality Control of 3,4-Diethoxybenzoic acid
| 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. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual ethanol, diethyl ether, and other process solvents per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Multi-element analysis after acid digestion; detection of Pb, Cd, As, Hg, and Cr by atomic emission spectroscopy following USP <232> limits. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection, calibrated against NaCl standards. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 600-700 C followed by sulfuric acid treatment and final weighing of inorganic residue per USP <281>. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using calibrated capillary apparatus with controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of crystalline solid against established reference standards under controlled lighting. |
| Acid Value | Acid-Base Titration | Titration with standardized sodium hydroxide solution using phenolphthalein indicator to determine free carboxylic acid content. |
| Loss on Drying | Thermogravimetric Analysis | Measurement of mass loss upon heating at 105 C for 2 hours under dry air or nitrogen, indicating volatile content including moisture and residual solvents. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine D10, D50, and D90 values per ISO 13320. |
