Industrial Applications of 4819-77-6
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Chemicals | Pharmaceutical Intermediate | Serves as a key intermediate for pyridine-carboxamide fungicides such as boscalid, participating in condensation or cyclization reactions. |
| Agrochemicals | Agrochemical Intermediate | Used in the synthesis of novel agrochemicals including azoxystrobin and boscalid, enabling construction of pyrimidine or pyridine ring systems. |
| Organic Synthesis | Carbonyl Source / Ethoxyacetylating Reagent | Hydrolyzes or reacts under acidic conditions to deliver ethoxyacetaldehyde or acetyl functionality. |
| Organic Synthesis | Protecting Group Reagent | Employs the stability of the acetal group to protect aldehyde functionalities, preventing oxidation or side reactions during multistep syntheses. |
Manufacturing Quality Control of 4819-77-6
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard under validated chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in anhydrous methanol-based solvent. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color intensity to APHA platinum-cobalt standard scale using visual or spectrophotometric assessment. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Measurement of mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index by measuring critical angle of total internal reflection at the prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis | Weighing non-volatile residue remaining after controlled evaporation of a known sample mass under specified temperature and time. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of trace metal content by measuring absorption of characteristic atomic spectral lines after acid digestion. |
| Non-Volatile Residue | Gravimetric Analysis | Same principle as Residue on Evaporation but conducted under stricter thermal conditions to ensure complete volatilization of product. |
| Aldehyde Impurities (e.g., acetaldehyde) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification/quantification of low-molecular-weight aldehyde impurities using retention time and mass spectral matching. |
| Ethanol Content | Gas Chromatography (GC) with FID | Quantitative analysis of residual ethanol using external calibration with ethanol reference standard. |
| Chloride Content | Ion Chromatography (IC) | Separation and conductivity detection of chloride ions after aqueous extraction and filtration. |
