| Materials Science | Building Block for Covalent Organic Frameworks (COFs) | Employed as part of tri- or tetra-functional monomers; participates in porous polymer network formation via alkyne–azide cycloaddition or boronate ester condensation |
| Electronic Materials | Precursor for Organic Semiconductors | Forms conjugated polyarylene–alkyne backbones via palladium-catalyzed coupling or electrochemical polymerization, applied in the active layer of organic field-effect transistors (OFETs) |
Manufacturing Quality Control of Ethyl 4-Ethynylbenzoate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities by HPLC coupled with diode array detection, using gradient elution and spectral comparison. |
| Residual Solvents | GC-FID | Quantitative determination of volatile organic solvents by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine trace water based on stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after anion exchange column separation. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard reference under controlled lighting and against white/black background. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing (700-800 C) and precise weighing of the cooled crucible. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light induced by chiral centers, reported as degrees per dm per g/mL concentration. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder size distribution by measuring angular variation in laser light scattering intensity. |
