Manufacturing Quality Control of (+)-Dibenzoyl-D-tartaric acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies D-dibenzoyltartaric acid by neutralizing its carboxylic acid groups with standardized sodium hydroxide solution. |
| Optical Rotation | [alpha]D Measurement using Polarimetry | Measures the degree of rotation of plane-polarized light, confirming chiral integrity and enantiomeric purity. |
| Loss on Drying | Gravimetric Analysis (Thermogravimetry) | Determines volatile content by measuring mass loss after drying at specified temperature and time. |
| Residue on Ignition | Weight Loss on Ignition | Measures inorganic ash content by incinerating sample at high temperature and weighing residual inorganic matter. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines content by weighing the dried precipitate. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, Hg, As) via elemental emission spectroscopy after acid digestion. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance. |
| Water Content | Karl Fischer Titration | Determines water by stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Melting Point | Capillary Melting Point Determination | Identifies purity and identity by observing temperature range over which solid transitions to liquid. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Detects and quantifies residual solvents (e.g., methanol, ethyl acetate) using flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular variation in laser light scattering pattern. |
