Industrial Applications of 3,5-Dibromo-4-cyanopyridine, 97%
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used to synthesize lead compounds for anticancer, antiviral, or central nervous system drugs | Employed as an aryl bromide in Suzuki coupling, cyano group transformation, or nucleophilic substitution to construct complex molecular frameworks |
| Pesticide Development | Serves as a synthetic intermediate for pyridine-containing insecticides or fungicides | Enables introduction of heterocyclic or alkyl side chains at the bromine site to enhance biological activity |
| Organic Synthesis Reagents | Used to build libraries of polysubstituted pyridine derivatives | Leverages selective functionalization at the dibromo sites to achieve regiocontrolled cross-coupling or cyclization reactions |
Manufacturing Quality Control of 3,5-Dibromo-4-cyanopyridine, 97%
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV, with identification based on retention time and peak area relative to main peak. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, DMF) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; water reacts stoichiometrically with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using isotopic detection for high sensitivity and selectivity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions after sample dissolution and filtration; quantified via external calibration. |
| Sulfate Impurity | Ion Chromatography | Anion exchange separation followed by suppressed conductivity detection; sulfate quantified using standard calibration curve. |
| Residue on Ignition | Gravimetric Analysis | Ignition of dried sample at 700-800 C, followed by weighing of inorganic residue as percentage of original mass. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically during controlled heating; reported as onset and clear point range. |
| Appearance | Visual Inspection | Assessment under controlled white light against white/black background; evaluated for color, clarity, and presence of particulates or discoloration. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to determine volume-based particle size distribution in dry or dispersed state. |
| Bulk Density | Tap Density Tester | Mass per unit volume measured after standardized tapping of a known mass in a graduated cylinder, following USP <616> guidelines. |
