Industrial Applications of 3-OXO-3-P-TOLYL-PROPIONIC ACID ETHYL ESTER
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate for synthesizing the anticoagulant drug rivaroxaban | Cyclizes with ortho-aminobenzoic acid derivatives under basic conditions to form the oxazolone ring |
| Agrochemical Intermediates | Heterocyclic precursor for synthesizing novel insecticides and fungicides | Prepared via multi-step reactions—including reduction and cyclization—to yield active ingredients containing triazole or oxazole structures |
| Organic Synthesis | β-Keto ester compound used in C–C bond-forming reactions such as Claisen condensation and Michael addition | Undergoes nucleophilic addition with organolithium or Grignard reagents, or serves as an acylating agent in transesterification reactions |
Manufacturing Quality Control of 3-OXO-3-P-TOLYL-PROPIONIC ACID ETHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a suitable capillary column and temperature program. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and gradient elution with UV absorbance at 220 nm. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling and FID detection | Headspace GC analysis to quantify residual ethyl acetate, ethanol, toluene, and other process solvents based on calibrated external standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated coulometrically to react stoichiometrically with water in the sample dissolved in KF reagent. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of free carboxylic acid groups in the sample using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Appearance | Visual Inspection in Glass Container | Assessment of physical state, color, and clarity against water-white standard under controlled daylight or D65 illumination. |
| Odor | Sensory Evaluation by Trained Personnel | Qualitative assessment of characteristic odor profile; rejection if off-odor (e.g., burnt, acrid, or oxidized notes) is detected. |
| Specific Gravity | Digital Density Meter (Oscillating U-tube principle) | Measurement of mass per unit volume at 20 degrees C by determining the resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Digital Refractometer at 20 degrees C | Determination of light bending angle at air-sample interface using monochromatic sodium D-line (589 nm) source and internal calibration. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element quantitative analysis after acid digestion and dilution, measuring emission intensities of metal-specific wavelengths. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on an ion-exchange column followed by suppressed conductivity detection for quantitative chloride determination. |
| Melting Point | Capillary Melting Point Apparatus (DSC optional) | Thermal transition measurement using capillary tube method with controlled heating rate; onset temperature reported as melting point. |
