Manufacturing Quality Control of D(+)-LACTIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies D(+)-lactide content using reversed-phase chromatography with UV detection at 210 nm. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation using a polarimeter to confirm chiral purity and enantiomeric excess. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration with iodine-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other heavy metals by plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid groups by titration with standardized NaOH solution using phenolphthalein indicator. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities (e.g., L-lactide, meso-lactide, oligomers) using gradient elution. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary method. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or discoloration against established reference standards. |
| Solvent Residues | GC-FID | Detects and quantifies residual solvents (e.g., chloroform, ethyl acetate) using gas chromatography with flame ionization detection. |
| Ash Content | Gravimetric Analysis | Measures total inorganic residue after complete combustion at 550-600 C and subsequent weighing. |
