| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate in the synthesis of active pharmaceutical ingredients (APIs) | Converted into specific drug molecules via chemical reactions |
| Pesticides | Key raw material in pesticide synthesis | Transformed through a series of chemical conversions to produce insecticidal, fungicidal, or herbicidal compounds |
| Fine Fragrances & Flavors | Used in the production of certain fragrance compounds | Generates odor-active substances via reactions such as esterification |
| Dyes | Involved in dye synthesis | Serves as one of the starting materials and undergoes coupling or other chemical steps to form the final product |
| Organic Synthesis | Multifunctional reagent in organic synthesis | Participates in various types of organic transformations under different reaction conditions |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities by comparing retention times and peak areas to qualified reference standards or threshold limits. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using gas chromatography with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-OES | Determines total heavy metal content (e.g., Pb, Cd, Hg, As) by plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or foreign matter under controlled lighting. |
| Acid Value | Acid-Base Titration | Measures carboxylic acid content by titration with standardized NaOH solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic residue after high-temperature ashing and weighing. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and absence of racemization. |
