Manufacturing Quality Control of (S)-(+)-2-Methylbutyric acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies (S)-(+)-2-methylbutyric acid by separation and flame ionization detection relative to a certified reference standard. |
| Specific Optical Rotation | [alpha]D measurement using polarimetry | Measures the angle of rotation of plane-polarized light at 20 C and 589 nm to confirm chiral integrity and enantiomeric excess. |
| Enantiomeric Excess (ee) | Chiral Gas Chromatography (cGC) | Separates (R) and (S) enantiomers on a chiral stationary phase and calculates ee from peak area ratio. |
| Water Content | Karl Fischer Titration (coulometric mode) | Electrochemically determines water content based on iodine generation stoichiometrically proportional to water. |
| Acid Value | Acid-Base Titration with NaOH | Neutralizes free carboxylic acid groups with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Measures non-volatile inorganic residue remaining after combustion at 700-800 C. |
| Heavy Metals | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Simultaneously quantifies trace metal impurities (e.g., Pb, Cd, As, Hg) via element-specific atomic emission. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Appearance | Visual Inspection against standard white background | Assesses physical state, color, and clarity in a transparent container under controlled lighting. |
| Boiling Point | Capillary Boiling Point Determination | Measures temperature at which vapor pressure equals atmospheric pressure using calibrated capillary apparatus. |
| Refractive Index | Refractometry at 20 C | Determines ratio of light velocity in air versus sample using Abbe refractometer at specified wavelength (589 nm). |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Quantifies volatile organic solvents (e.g., hexane, methanol) by equilibrium partitioning into headspace followed by GC analysis. |
