Industrial Applications of 622-75-3
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate for synthesizing active pharmaceutical ingredients (APIs), including antidepressants and antipsychotics | Serves as a key building block in multistep organic synthesis, such as reduction, hydrolysis, or cyclization reactions |
| Pesticides | Intermediate for manufacturing agrochemicals, including herbicides and insecticides | Introduces functional groups via nitrile transformations—e.g., hydrolysis to carboxylic acids or reduction to amines |
| Dyes & Pigments | Intermediate for synthesizing high-performance dyes and fluorescent materials | Participates in condensation or coupling reactions to construct conjugated chromophore systems |
| Polymers | Monomer for specialty engineering plastics or functional polymers | Undergoes functional group transformation prior to polymerization (e.g., polyamide or polyester synthesis) |
| Organic Synthesis | Multifunctional synthon for constructing complex molecules containing a benzene ring and acetonitrile side chain | Enables diverse molecular synthesis through selective reactions of the two nitrile groups |
Manufacturing Quality Control of 622-75-3
| 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 using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected by current change. |
| Residue on Ignition | Gravimetric Analysis | Sample is incinerated at 750-800 C, and the non-volatile residue is weighed after cooling in a desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of chloride anions on an anion-exchange column followed by conductivity detection. |
| Sulfate Impurity | Ion Chromatography (IC) | Separation of sulfate anions on an anion-exchange column followed by conductivity detection. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and UV absorbance at 220 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, observed visually under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of sample against specified criteria in a white background under diffused daylight. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Iron Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantification after microwave-assisted acid digestion by measuring characteristic atomic emission lines in plasma. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measurement of mass loss upon heating at 105 C for 2 hours under atmospheric conditions. |
