Manufacturing Quality Control of 2-HYDROXY-3-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 redox reaction in methanol-based solvent, with coulometric or volumetric detection. |
| Optical Rotation | Polarimetry | Determines specific rotation using sodium D-line light to assess enantiomeric purity and identity of chiral center. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by high-temperature ashing followed by weighing of residual ash. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) by measuring absorption of element-specific wavelengths in atomized sample. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column with conductivity detection. |
| Related Substances | Gas Chromatography (GC) with FID | Separates and detects organic impurities based on volatility and polarity; quantified relative to main peak using flame ionization detection. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Extracts and quantifies volatile solvents (e.g., methanol, ethyl acetate) from sample matrix via equilibrium headspace analysis. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting and white background. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Acid Value | Acid-Base Titration with KOH | Determines free acid content as mg KOH per g sample by titration with standardized potassium hydroxide in ethanol. |
| Specific Gravity | Digital Density Meter | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
