Manufacturing Quality Control of 57526-28-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (2-Methylbutyryl Chloride Content) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., HCl, carboxylic acids) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature incineration of a weighed sample. |
| Water Content | Karl Fischer Titration | Electrochemical titration quantifying water via iodine-sulfur dioxide reaction in anhydrous methanol/pyridine medium. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Assessment of yellowness by matching sample color to APHA platinum-cobalt standard solutions or measuring absorbance at 455 nm. |
| Density at 20 degC | Digital Density Meter | Determination of mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 degC | Refractometry | Measurement of light bending angle at air-sample interface using Abbe refractometer or digital equivalent. |
| Chloride Ion (as Cl-) | Ion Chromatography (IC) | Separation and quantification of chloride anions on an anion-exchange column with suppressed conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using flame or graphite furnace AAS with lead-specific hollow cathode lamp. |
| Non-Volatile Residue | Gravimetric Analysis | Weighing residue remaining after evaporation of a fixed sample volume under controlled heating and drying conditions. |
| Aldehyde Impurities | Gas Chromatography (GC) with FID or HS-GC | Separation and quantification of low-boiling aldehydes (e.g., isobutyraldehyde) using headspace or direct injection GC. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by organic peroxides in acetic acid/chloroform, followed by titration with sodium thiosulfate. |
