Industrial Applications of 5-Cyano-2-methyl-benzoic acid methyl ester
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate in the synthesis of the antiplatelet drug ticagrelor | Undergoes cyclization with aqueous ammonia or hydrazine reagents to construct the triazolopyrimidine core; followed by hydrolysis, coupling, and other sequential reactions to produce ticagrelor |
| Pesticide R&D | Structural modification precursor for novel insecticides and plant growth regulators | Acts as a multifunctional aromatic building block containing cyano and ester groups, participating in nucleophilic substitution, reduction, coupling, and other reactions to introduce bioactive side chains |
Manufacturing Quality Control of 5-Cyano-2-methyl-benzoic acid methyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 220-254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3A/B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, toluene, ethyl acetate) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent where water reacts stoichiometrically to determine trace moisture content. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, based on mass-to-charge ratio detection with high sensitivity and low detection limits. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in solution after sample dissolution and dilution; quantified against sodium chloride standard. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 600-700 C followed by sulfuric acid treatment and weighing of non-volatile residue to assess inorganic impurities. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition temperature range using calibrated capillary method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of bulk sample against established reference standards under controlled lighting conditions. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution; used to confirm stereochemical integrity if applicable. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample via light scattering pattern to determine volume-weighted particle size distribution (D10, D50, D90). |
| Residual Catalyst (Pd) | ICP-OES | Quantification of palladium after microwave-assisted acid digestion using inductively coupled plasma optical emission spectroscopy at characteristic emission wavelengths. |
