Manufacturing Quality Control of (S)-2-HYDROXYBUTYRIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies S-2-hydroxybutyric acid by neutralization with standardized NaOH using phenolphthalein or potentiometric endpoint detection. |
| Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light caused by chiral S-2-hydroxybutyric acid in solution. |
| Water Content | Karl Fischer Titration | Determines trace water via stoichiometric iodine reaction with sulfur dioxide and a base in methanol. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities remaining after high-temperature ashing and weighing. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metals such as Pb, Cd, Hg, and As by measuring absorption of element-specific UV-Vis radiation. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Chloride Turbidimetry | Forms insoluble BaSO4 precipitate; sulfate concentration is proportional to turbidity measured spectrophotometrically. |
| Related Substances | High Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally similar impurities using reversed-phase C18 column and UV detection. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Determination | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Measures hydrogen ion activity in dilute aqueous solution using calibrated glass electrode and reference electrode. |
| Specific Gravity | Digital Density Meter | Determines ratio of sample density to water density at specified temperature using oscillating U-tube principle. |
