Manufacturing Quality Control of 4-TRIMETHYLSILYL-3-BUTYN-1-OL

Detection Item	Common Analytical Method	Method Overview
Assay (Purity)	Gas Chromatography (GC) with FID detection	Quantifies main component by retention time and peak area against calibrated standard.
Water Content	Karl Fischer Titration	Measures water via electrochemical reaction between iodine, sulfur dioxide, and water in methanol-based reagent.
Residue on Ignition	Gravimetric Analysis	Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing.
Acidity (as Acetic Acid)	Acid-Base Titration with NaOH	Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator.
Heavy Metals	ICP-OES	Quantifies trace metal contaminants (e.g., Pb, Fe, Cu) by atomic emission intensity after acid digestion.
Chloride Content	Ion Chromatography (IC)	Separates and quantifies chloride ions based on retention time and conductivity detection.
Refractive Index	Refractometry	Measures bending of light through sample at specified temperature to assess purity and consistency.
Specific Gravity	Pycnometry	Determines density relative to water using calibrated glass pycnometer at controlled temperature.
Color (APHA)	Visual Comparison or Spectrophotometry	Evaluates yellowness by matching sample color to APHA platinum-cobalt standard scale.
Volatility Residue	Thermogravimetric Analysis (TGA)	Measures mass loss upon heating to assess volatile impurities and thermal stability.
Aldehyde Impurities	Derivatization GC-MS	Converts aldehydes to stable hydrazones followed by separation and selective detection.
Silicon Content	ICP-OES	Quantifies total silicon (including residual silane catalysts) via characteristic atomic emission line.
