Industrial Applications of Butanedioic acid,(phenylmethylene)-,(E)-
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used in the synthesis of anticancer drugs, protein kinase inhibitors, and other active pharmaceutical ingredients | Employed as a chiral building block in coupling reactions, cycloadditions, and asymmetric hydrogenation |
| Organic Synthesis | Applied as a versatile synthon for introducing the benzylidene succinic acid structural motif | Structurally modified via Diels–Alder reactions, decarboxylative functional group transformations, or selective hydrolysis/esterification |
| Materials Science | Potentially used in the preparation of functional polymers (e.g., degradable polyesters, liquid crystal monomers) | Utilized as a comonomer in condensation polymerization with diols, or after derivatization, in ring-opening polymerization |
Manufacturing Quality Control of Butanedioic acid,(phenylmethylene)-,(E)-
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, calibrated against certified reference standard. |
| Identity | FT-IR Spectroscopy | Comparison of sample infrared spectrum to reference spectrum based on characteristic functional group absorptions (e.g., C=O, C=C). |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, confirming structural integrity and purity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to quantify trace water via stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 750-800 C. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy quantifying total heavy metal content after acid digestion and calibration with lead standards. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anion using suppressed conductivity detection after aqueous extraction. |
| Related Substances | HPLC-DAD | Detection and quantification of structurally similar impurities using diode array detection and relative response factors. |
| Organic Volatile Impurities | GC-FID | Headspace or direct injection GC with flame ionization detection for residual solvents and low-boiling impurities. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light to confirm chiral purity and identity (though compound is E-configured, not chiral). |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator to determine free carboxylic acid content. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting. |
