| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Pharmaceutical intermediates | Used as starting materials for the synthesis of active pharmaceutical ingredients |
| Agrochemicals | Agrochemical intermediates | Applied as structural building blocks in the preparation of herbicides or insecticides |
| Fine chemicals | Synthesis of specialty chemicals | Employed as key building blocks in organic synthesis |
| Chemical research | Laboratory research | Utilized in the development of novel reaction methodologies or compound screening |
| 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 detector. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities by retention time and UV absorbance relative to the main peak. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvent residues are vaporized in sealed vials and quantified via GC-FID using external calibration standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities using standardized sodium hydroxide solution, with phenolphthalein or potentiometric endpoint detection. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Sample is ignited at 700-800 C after sulfuric acid treatment; residual inorganic ash is weighed following cooling in desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Sample digested with nitric and sulfuric acids; lead concentration determined by AAS at characteristic wavelength (283.3 nm). |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Chloride ions separated on anion-exchange column and quantified by conductivity response relative to calibration standards. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and enantiomeric excess. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change; determined by controlled heating and visual or automatic detection. |
| Appearance | Visual Inspection (against white/black background) | Assessment of physical state, color, and clarity in transmitted and reflected light under controlled lighting conditions. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Density derived from resonant frequency shift of a U-shaped glass tube filled with sample at controlled temperature. |
