Industrial Applications of 1131-15-3
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a chiral intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (e.g., ibuprofen, naproxen) and other optically active pharmaceuticals | Serves as a key building block in chiral resolution or asymmetric synthesis, participating in acylation, esterification, and related reactions |
| Agrochemicals | Used to synthesize chiral agrochemical intermediates with biological activity | Acts as a chiral source in the stereoselective synthesis of agrochemical molecules |
| Materials Science | Used to prepare chiral polymeric materials or liquid crystal monomers | Introduces chiral centers via ring-opening polymerization or condensation polymerization to modulate optical properties of materials |
| Organic Synthesis | Used as a chiral auxiliary or chiral reagent | Provides a stereocontrolled environment in asymmetric catalysis or chirality-inducing reactions |
Manufacturing Quality Control of 1131-15-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV absorbance at 210-230 nm. |
| Appearance | Visual inspection | Assessment of physical state, color, and presence of visible particulates or foreign matter under controlled lighting conditions. |
| Melting Point | Capillary melting point apparatus | Determination of temperature range over which solid transitions to liquid, indicating purity and identity via comparison to literature value (approx. 98-102 C). |
| Loss on Drying | Gravimetric thermogravimetry | Measurement of mass loss after drying under specified temperature and vacuum conditions, reflecting volatile impurities and residual solvents. |
| Residue on Ignition | Sulfated ash gravimetry | Quantification of inorganic residue remaining after high-temperature combustion, indicating inorganic impurities. |
| Chloride Impurity | Ion chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection of heavy metals after acid digestion, with quantification based on atomic emission intensity at characteristic wavelengths. |
| Water Content | Karl Fischer titration | Volumetric or coulometric determination of water via stoichiometric reaction with iodine in pyridine/methanol-based reagent. |
| Acid Value | Acid-base titration with NaOH | Neutralization of acidic functional groups (e.g., residual acid or hydrolyzed anhydride) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Related Substances | HPLC with gradient elution | Identification and quantification of structurally related impurities (e.g., benzylsuccinic acid, phthalic anhydride, unreacted precursors) using retention time and relative response factors. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light, confirming enantiomeric composition if applicable (though compound is typically achiral, used for batch consistency). |
