Industrial Applications of 3637-61-4
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Pharmaceutical Intermediates | Used to synthesize pharmaceutical intermediates such as cyclopentylmethylamine, or as a hydrophobic side-chain introducing agent in drug molecular structures. |
| Agrochemical Industry | Agrochemical Synthesis Intermediates | Used to synthesize cyclopentyl-substituted agrochemical active ingredients, serving as a functional group for modifying agrochemical molecular structures. |
| Organic Synthesis | Alkylating Agent | Introduces the cyclopentylmethyl group into target molecules via hydroxyl groups or their halogenated or oxidized derivatives. |
| Fragrance & Flavor Industry | Fragrance Raw Material | Used to synthesize ester compounds with specific fruity or woody notes (e.g., carboxylic acid esters formed via esterification). |
| Coatings Industry | Solvent and Modifier | Serves as a high-boiling-point alcoholic solvent or as a monomer for synthesizing specialty resins, improving coating leveling and solubility. |
Manufacturing Quality Control of 3637-61-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies cyclopentylmethanol content by retention time and peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction in pyridine-methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standards or measuring absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume using the resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 C | Refractometry (Abbe type) | Measures bending of light passing through sample to determine refractive index, correlated to purity and composition. |
| Residue on Evaporation | Gravimetric Analysis | Quantifies non-volatile residue after controlled evaporation of a defined sample volume under specified temperature and vacuum. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Detects trace heavy metals by measuring absorption of characteristic wavelength light by ground-state atoms in flame or graphite furnace. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions by titration with silver nitrate using silver electrode for endpoint detection. |
| Aldehyde Impurities | Gas Chromatography (GC) with FID or HPLC-UV | Separates and quantifies aldehyde impurities (e.g., cyclopentanecarbaldehyde) using chromatographic retention and detector response. |
| Non-Volatile Residue | Gravimetric Analysis after Solvent Evaporation | Measures insoluble particulates or high-boiling residues after evaporating solvent and drying residue to constant weight. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral molecules; confirms absence of significant enantiomeric contamination. |
