Manufacturing Quality Control of 2,4,7,9-Tetramethyl-5-decyne-4,7-diol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 430 nm | Evaluates yellowness intensity by matching sample color to APHA platinum-cobalt standards or measuring absorbance at 430 nm. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing of the cooled crucible. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions by titration with silver nitrate using silver indicator electrode and reference electrode. |
| Refractive Index | Refractometry | Measures ratio of light velocity in air vs. sample at specified temperature using calibrated refractometer. |
| Specific Gravity | Digital Density Meter or Pycnometer | Determines mass per unit volume relative to water at specified temperature. |
| Flash Point | Closed Cup Pensky-Martens Tester | Identifies lowest temperature at which vapors ignite momentarily under controlled heating and ignition source. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of particulates or phase separation in a standard glass container under controlled lighting. |
| Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Detects and identifies low-boiling organic impurities by thermal equilibration in headspace vial followed by GC separation and MS detection. |
