Industrial Applications of diethyl 2-broMo-5-chloroterephthalate
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key structural building blocks for synthesizing antitumor agents, kinase inhibitors, and other active pharmaceutical ingredients | Used as a multifunctional aryl building block bearing bromo and chloro substituents, enabling further functionalization via Suzuki coupling, Heck reaction, or nucleophilic substitution |
| Organic Synthesis | Starting material for constructing halogenated heterocycles and complex aromatic frameworks | Converted into high-value fine chemicals through multistep transformations, including palladium-catalyzed cross-coupling, selective hydrolysis/ester exchange, reduction, or ammonolysis |
| Materials Science | Structural modifier for liquid crystal monomers and organic optoelectronic materials | Introduces a rigid terephthalic acid backbone; halogen atoms are used to tune molecular polarity, dielectric anisotropy, and thin-film formation properties |
Manufacturing Quality Control of diethyl 2-broMo-5-chloroterephthalate
| 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 | Identifies and quantifies impurities by retention time and peak area relative to main peak using gradient elution. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., ethanol, ethyl acetate) via headspace GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation in pyridine-free reagent. |
| Heavy Metals | ICP-OES | Measures total elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion by optical emission intensity at element-specific wavelengths. |
| Chloride Content | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant with silver indicator electrode and reference electrode. |
| Bromide Content | Ion Chromatography | Separates and detects bromide anions in hydrolyzed sample using suppressed conductivity detection. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid groups by titration with standardized NaOH solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder using standardized cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder using Mie scattering theory applied to laser beam diffraction pattern. |
