Manufacturing Quality Control of ALPHA-HYDROXY-GAMMA-BUTYROLACTONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 2-hydroxybutyric ketone by separation and flame ionization detection relative to a certified reference standard. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines water via electrochemical titration using iodine generated in situ, based on stoichiometric reaction with water. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Separates and quantifies volatile organic solvents (e.g., acetone, ethanol) by equilibrium partitioning into headspace followed by GC analysis. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Measures trace metal impurities after acid digestion by detecting element-specific atomic emission lines in high-temperature plasma. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH and phenolphthalein indicator | Neutralizes acidic impurities; endpoint detected by color change, calculating acidity equivalent to acetic acid. |
| Optical Rotation | [α]D at 20 °C | Measures specific rotation of plane-polarized light using a digital polarimeter to confirm chiral integrity and enantiomeric composition. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Determines non-volatile inorganic residue after controlled ignition and sulfuric acid treatment, expressed as mass percent. |
| Appearance and Color | Visual Inspection against APHA Scale | Compares sample clarity and yellowish tint to standardized platinum-cobalt solutions under controlled lighting. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities (e.g., 2-hydroxybutyric acid, butanone) using reversed-phase chromatography and UV absorbance. |
| Refractive Index | Refractometry at 20 °C | Measures bending of light through the liquid sample at specified temperature to assess purity and consistency of molecular composition. |
