Manufacturing Quality Control of 131787-39-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Appearance | Visual Inspection | Assessment of liquid clarity and absence of visible particulates or phase separation under controlled lighting. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 430 nm. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Neutralizes free carboxylic acid groups using standardized potassium hydroxide solution; calculates mg KOH per g sample. |
| Hydroxyl Value | Acetylation followed by back-titration | Derivatizes OH groups with acetic anhydride, then titrates unreacted anhydride with NaOH. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically determines water via iodine generation and stoichiometric reaction with sample water. |
| Residue on Ignition | Gravimetric Analysis after Ashing | Measures non-volatile inorganic residue mass after high-temperature combustion in muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample and measuring absorbance of characteristic wavelength light. |
| Peroxide Value | Iodometric Titration | Oxidizes iodide to iodine by peroxides; titrates liberated iodine with standardized sodium thiosulfate. |
| Refractive Index | Refractometry at 20 C | Measures bending of light through sample at specified temperature using calibrated refractometer. |
| Density | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume from resonant frequency shift of vibrating U-tube filled with sample. |
| Volatile Organic Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Separates and identifies low-boiling impurities via thermal headspace injection and mass spectral detection. |
