Manufacturing Quality Control of 1186-73-8
| 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 (Coulometric mode) | Electrochemical titration based on iodine consumption in reaction with water. |
| Acid Value | Acid-Base Titration (NaOH in ethanol/water) | Measures free carboxylic acid impurities via neutralization with standardized sodium hydroxide. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determines non-volatile inorganic impurities by mass difference after high-temperature ashing. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies trace metal contaminants by atomic emission intensity at element-specific wavelengths. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement (430 nm) | Evaluates yellowness by matching sample absorbance at 430 nm to APHA color scale standards. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determines mass per unit volume via resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry (Abbe refractometer) | Measures bending of light at air-sample interface to determine optical density at specified temperature. |
| Residual Solvents (e.g., methanol) | Headspace Gas Chromatography (HS-GC) with FID | Quantifies volatile organic impurities by equilibrium partitioning into headspace followed by GC separation. |
| Related Substances | Gas Chromatography–Mass Spectrometry (GC-MS) | Identifies and quantifies structurally related impurities (e.g., mono/di-methyl esters, hydrolysis products) via retention time and mass spectral matching. |
| Appearance | Visual Inspection (in clear glass container under controlled lighting) | Assesses physical state, clarity, and presence of particulates or phase separation against specification limits. |
| Boiling Point Range | Capillary Gas Chromatography (Simulated Distillation mode) | Estimates boiling point distribution by correlating GC retention times with n-alkane standards under programmed temperature conditions. |
