Industrial Applications of 1H-Pyrazole,3-methyl-5-nitro-(9CI)
| Industry | Application | Process |
|---|---|---|
| Pesticides | Intermediate for novel insecticides, used in synthesizing pyrazole-based insecticides (e.g., flufiprole) | Undergoes substitution or coupling reactions with haloalkanes, amines, etc., to construct the target molecular scaffold |
| Pharmaceuticals | Intermediate for drug synthesis, employed in structural modification of anti-inflammatory and antitumor active compounds | Participates in cycloaddition, reduction, acylation, and other reactions to introduce pharmacophoric groups |
| Materials Science | Precursor for high-energy materials, used in synthesizing energetic compounds (e.g., nitro-substituted pyrazole derivatives) | Nitro group is reduced to amino group, followed by reaction with anhydrides or acid chlorides to prepare energetic polymer monomers |
Manufacturing Quality Control of 1H-Pyrazole,3-methyl-5-nitro-(9CI)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV or HPLC-MS | Separation and detection of structurally related impurities (e.g., isomers, nitro-reduction by-products, unreacted precursors) using gradient elution and UV or mass-selective detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual solvents (e.g., ethanol, ethyl acetate, DMF) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (e.g., Pb, Cd, As, Hg) after acid digestion, based on elemental mass spectrometric detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine–sulfur dioxide reaction in pyridine/methanol medium to determine trace water content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via controlled heating; sharp melting range confirms crystalline identity and absence of significant eutectic impurities. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content after high-temperature incineration (700–800 °C) and weighing of residual non-volatile matter. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity-based quantification of chloride ions leached from potential chlorinated impurities or reagents. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light to confirm chiral purity (if applicable) and detect racemization or asymmetric synthesis deviations. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine D10, D50, D90 values, critical for downstream processing (e.g., filtration, formulation). |
