Industrial Applications of METHYL 2,5-DICHLOROBENZOATE
| Industry | Application | Process |
|---|---|---|
| Pesticides | Key intermediate in the synthesis of the fungicide boscalid | Used to prepare boscalid via multi-step reactions including cyclization and substitution with compounds such as methyl 3-amino-2-chlorobenzoate |
| Pharmaceuticals | Structural building block for synthesizing anticancer and antibacterial agents | Acts as an aryl substituent in coupling reactions (e.g., Suzuki coupling) or, after hydrolysis or aminolysis, enables construction of active molecular scaffolds |
| Organic Synthesis | Multifunctional organic synthesis intermediate for introducing the 2,5-dichlorobenzoyl group or modifying the benzene ring | Can be selectively hydrolyzed to 2,5-dichlorobenzoic acid, or further functionalized via reduction, halogen exchange, or metalation |
Manufacturing Quality Control of METHYL 2,5-DICHLOROBENZOATE
| 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 non-polar capillary column. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities using reversed-phase C18 column and gradient elution with UV absorbance at 254 nm. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling and FID | Headspace equilibration followed by GC separation to quantify volatile organic solvents (e.g., methanol, dichloromethane) based on external calibration. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample dissolved in KF reagent. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of free carboxylic acid groups (if hydrolyzed) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Chlorine Content | Oxygen Flask Combustion followed by Potentiometric Titration | Combustion in oxygen flask converts organically bound chlorine to chloride ion, which is then titrated with silver nitrate using potentiometric endpoint detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Sample digested with nitric/hydrochloric acid mixture; lead concentration measured by flame or graphite furnace AAS at 283.3 nm. |
| Sulfated Ash | Gravimetric Analysis (Ignition at 700 degC) | Sample ignited with sulfuric acid to convert metals to stable sulfates; residue weighed after cooling in desiccator. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed visually or automatically as the temperature at which solid phase changes to liquid under controlled heating rate. |
| Appearance | Visual Inspection in Standardized Lighting | Assessment of physical state, color, and clarity against white/black background under D65 daylight illumination. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution of known concentration and path length at specified wavelength (589 nm) and temperature. |
| Residue on Ignition | Gravimetric Analysis (Ignition at 700 degC) | Mass of non-volatile inorganic residue determined after ignition and cooling; expressed as weight percent of original sample. |
