| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of pharmaceutical intermediates | Used in the preparation of anti-inflammatory agents, analgesics, etc. |
| Pesticides | Preparation of pesticide intermediates | Applied in the synthesis of insecticides or herbicides |
| Fine Fragrances | Synthesis of fragrance compounds | Generates aromatic compounds via esterification or condensation reactions |
| Organic Synthesis | General-purpose reagent | Participates in Michael addition, cyclization, and other reactions |
| Dyes | Synthesis of dye intermediates | Used in the production of azo dyes or other functional dyes |
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and clarity (transparent or not) under natural light or standard illumination to check for impurities or discoloration. |
| Assay | Gas Chromatography (GC) | Quantify the main component using a capillary column (e.g., DB-5), a flame ionization detector (FID), and either internal or external standard method. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Use a C18 reversed-phase column with a UV detector (210–254 nm), and a mobile phase consisting of methanol-water or acetonitrile-water system to evaluate separation between impurity peaks and the main peak. |
| Moisture Content | Karl Fischer Titration | Accurately determine water content in the sample based on the reaction of iodine and sulfur dioxide with water in a pyridine/methanol system, using coulometric or volumetric titration. |
| Acid Value | Acid-Base Titration | Dissolve the sample in ethanol and titrate free acids with a standardized sodium hydroxide solution; calculate the milligrams of KOH consumed per gram of sample. |
| Refractive Index | Refractometry | Measure the refractive index (n20D) at 20°C using an Abbe refractometer for identity confirmation and purity assessment. |
| Density | Pycnometer Method or Digital Density Meter | Determine mass per unit volume at a specified temperature (e.g., 20°C) for verification of physical properties. |
| Boiling Point / Initial Boiling Point | Distillation Method or Differential Scanning Calorimetry (DSC) | Determine boiling range by atmospheric or vacuum distillation, or analyze phase transition temperatures using DSC to assess volatility and thermal stability. |
| Volatile Organic Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Combine the separation capability of GC with the identification power of MS to detect residual solvents or other organic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, measure trace levels of heavy metal elements such as lead, arsenic, mercury, and cadmium to ensure compliance with safety limits. |
| Melting Point (if solid) | Capillary Melting Point Method | Although diethyl phenylmalonate is typically liquid, if crystallization occurs, the melting range can be determined using a melting point apparatus. |
