Manufacturing Quality Control of 2-Hydroxy-2-methylbutyric acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies carboxylic acid group by neutralization with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Water Content | Karl Fischer Titration | Measures water via iodine-sulfur dioxide reaction in methanol-based reagent, with coulometric or volumetric detection of endpoint. |
| Appearance | Visual Inspection | Assesses physical state and clarity by observing sample in a clean, colorless glass container under controlled lighting conditions. |
| Color | Hazen (APHA) Color Scale | Compares sample color to platinum-cobalt standard solutions using a colorimeter or visual comparator. |
| Specific Gravity | Digital Density Meter | Determines density relative to water at 20 degrees C using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at 20 degrees C to determine purity and concentration. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic impurities by high-temperature ashing followed by weighing of residual ash. |
| Heavy Metals | ICP-OES | Detects trace metal contaminants (e.g., Pb, Cd, Hg, As) after acid digestion by measuring elemental emission spectra. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection. |
| Related Substances | Gas Chromatography (GC-FID) | Separates and detects organic impurities including isomers and degradation products using flame ionization detection. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral compound using sodium D-line light to confirm stereochemical identity and enantiomeric purity. |
| pH of Aqueous Solution | pH Meter | Determines hydrogen ion activity in a defined aqueous solution (e.g., 10% w/v) using calibrated glass electrode. |
