Industrial Applications of 995-45-9
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Silyl protecting reagent for selective protection of hydroxyl groups in alcohols and phenols | Reacts with hydroxyl-containing compounds under anhydrous conditions to form tert-butyldimethylsilyl (TBDMS) ethers; deprotection is achieved using fluoride ions (e.g., TBAF) or acidic conditions |
| Pharmaceutical Industry | Hydroxyl-protecting agent in intermediate synthesis to enhance reaction selectivity and yield | Temporarily masks reactive hydroxyl groups during multistep synthesis to suppress side reactions, followed by deprotection after completion of other functional group transformations |
| Materials Science | Surface modifier for tuning material surface hydrophobicity or reactivity | Reacts with hydroxyl-terminated inorganic surfaces (e.g., glass, silica) to introduce hydrophobic tert-butyldimethylsilyl groups |
| Analytical Chemistry | Derivatization reagent for gas chromatography (GC) or mass spectrometry (MS) analysis of polar compounds | Converts polar hydroxyl-containing compounds into more volatile tert-butyldimethylsilyl ether derivatives to facilitate detection |
Manufacturing Quality Control of 995-45-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Acid Value | Acid-Base Titration | Measures acidic impurities by titration with standardized KOH solution in alcoholic medium. |
| Chloride Content | Potentiometric Titration | Determines chloride ions via argentometric titration using silver nitrate and silver indicator electrode. |
| Water Content | Karl Fischer Titration | Measures trace water by iodine-sulfur dioxide redox reaction in anhydrous methanol/pyridine medium. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation of a known sample mass under specified conditions. |
| Color | Visual Comparison or Spectrophotometry | Evaluates color intensity against platinum-cobalt standard scale or measures absorbance at specified wavelength. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through sample at 20 C using calibrated refractometer. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring atomic absorption at characteristic wavelengths. |
| Iron Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Detects Fe after sample digestion by measuring element-specific emission intensities in plasma. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies low-boiling impurities based on retention time and mass spectral fragmentation. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous dilution using calibrated pH electrode. |
