Manufacturing Quality Control of 3-CYCLOPROPYL-3-OXO-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 calibrated column and carrier gas. |
| 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. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling and FID detection | Headspace equilibration followed by GC separation to quantify volatile organic solvents (e.g., ethanol, ethyl acetate) against internal standard. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic functional groups (e.g., residual acid) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison against APHA/Pt-Co Standard Solutions | Subjective assessment of sample color intensity by matching against standardized platinum-cobalt scale solutions under controlled lighting. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Measurement of mass per unit volume via resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Digital Refractometer (Abbe-type principle) | Determination of light bending angle at air-sample interface using monochromatic sodium D-line illumination. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element quantitative analysis after acid digestion, based on element-specific atomic emission intensities. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash method) | Weighing of non-volatile inorganic residue remaining after high-temperature incineration with sulfuric acid treatment. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation and quantification of chloride anions using anion-exchange column and suppressed conductivity detection. |
| Optical Rotation | Polarimetry (Sodium D-line, 20 deg C) | Measurement of angular rotation of plane-polarized light caused by chiral molecules in solution at specified concentration and path length. |
