| Organic Synthesis | Serves as a starting material for synthesizing other compounds containing both alkyne and carboxylic acid functional groups | Subjected to click chemistry reactions (e.g., CuAAC) via its alkyne group, or engaged in esterification, amidation, and related reactions via its carboxylic acid group |
| Fine Chemicals | Used in the production of dyes, fragrances, and functional additives | Employed in esterification or condensation reactions with aromatic compounds or alcohols to construct complex molecular architectures |
Manufacturing Quality Control of 3-ETHYNYL-BENZOIC ACID
| 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 254 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 | Detection and quantification of volatile organic solvents (e.g., acetone, toluene) using gas chromatography with flame ionization detection and external calibration. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, based on atomic emission intensities at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Residue mass determination after incineration at 700-800 C followed by sulfuric acid treatment and constant weight measurement. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs, measured using calibrated capillary apparatus. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against standard reference samples. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator; calculation based on consumed titrant volume. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns from dispersed particles to derive volume-based size distribution. |
| Residual Palladium | ICP-MS | Ultra-trace quantification of Pd catalyst residue after microwave-assisted digestion, using isotope-dilution or external calibration with high mass resolution. |
