Manufacturing Quality Control of 2-METHYL-4-PENTENOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantifies 2-methyl-4-pentanoic acid peak area relative to a calibrated standard using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration with iodine, based on the stoichiometric reaction of water with Karl Fischer reagent. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid content by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to APHA platinum-cobalt standards or measures absorbance at 430 nm in a 10 cm cell. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle with temperature-controlled sample. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement at specified wavelength (e.g., sodium D line). |
| Residue on Evaporation | Gravimetric Analysis | Evaporates a known volume under controlled conditions and weighs non-volatile residue after drying. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample in flame or graphite furnace and measuring absorption at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride anions using anion-exchange column and conductivity detection. |
| Non-Volatile Matter | Gravimetric Analysis | Dries a weighed sample at 105 C to constant weight and calculates residue percentage. |
| Odor | Sensory Evaluation | Assesses conformity to reference standard by trained personnel under controlled conditions. |
| Flash Point | Pensky-Martens Closed Cup Tester | Determines lowest temperature at which vapors ignite momentarily when exposed to flame under standardized closed-cup conditions. |
