Manufacturing Quality Control of 3-METHYLTHIOPROPIONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 3-methylthiopropionic acid peak area against a calibration curve using an internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on the iodine-sulfur dioxide reaction in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid content by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Specific Gravity | Digital Density Meter | Measures mass per unit volume at specified temperature (e.g., 20 C) using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using Abbe refractometer at controlled temperature. |
| Color (APHA) | Visual Comparison or Spectrophotometric APHA | Evaluates yellowness by matching sample color to platinum-cobalt standard solutions or measuring absorbance at 455 nm. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume under controlled conditions and weighs non-volatile residue after drying. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring atomic absorption of lead-specific wavelength. |
| Sulfur Content | Combustion IC (Ion Chromatography) | Oxidizes organic sulfur to sulfate, then detects sulfate ions via conductivity detection after separation. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects volatile impurities (e.g., methanol, acetone) by analyzing vapor phase above sample at equilibrium. |
| Odor | Organoleptic Evaluation | Assesses characteristic pungent odor qualitatively against reference standard by trained personnel. |
| Appearance | Visual Inspection | Evaluates clarity and presence of suspended particles or phase separation in undiluted sample under controlled lighting. |
