Industrial Applications of 21075-86-5
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Chemicals | Pharmaceutical Intermediates | Used as a hydrazine protecting reagent in the synthesis of hydrazine-containing drug molecules; participates in deprotection to yield 1-allylhydrazine. |
| Pharmaceutical Chemicals | Organic Synthesis Building Blocks | Applied in condensation reactions between hydrazine and carbonyl groups to construct heterocyclic compounds (e.g., pyrazole or triazole derivatives). |
| Chemical Reagents | Protecting Group Chemistry | Introduced as a tert-butoxycarbonyl (Boc) protecting group in multistep syntheses to prevent side reactions of the hydrazine functionality; removed via acidolysis or catalytic hydrogenation after completion of the reaction sequence. |
Manufacturing Quality Control of 21075-86-5
| 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 calibrated column and carrier gas. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and gradient elution. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile organic solvents are equilibrated in headspace vial, then injected and quantified via GC-FID against calibration standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein endpoint detection. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample is ignited at 700-800 C to volatilize organic matter; inorganic residue is weighed after cooling in desiccator. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metal ions in argon plasma; emission intensity measured at characteristic wavelengths for quantitative analysis. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Anion separation on ion-exchange column followed by quantitative detection via suppressed conductivity measurement. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and enantiomeric excess. |
| Appearance | Visual Inspection (against USP/EP standards) | Comparison of sample solution clarity and color with specified standards under controlled lighting and against white/black backgrounds. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Hydrogen ion activity determined using calibrated glass electrode and reference electrode in aqueous suspension. |
| Bulk Density | USP <616> Tap Density Method | Mass per unit volume measured after controlled tapping of a graduated cylinder containing the powder sample. |
