Manufacturing Quality Control of (+)-(6R)-2,6-Diamino-4,5,6,7-tetrahydrobenzothiazole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Chiral Purity (Enantiomeric Excess) | Chiral HPLC | Separation of (6R)- and (6S)-enantiomers on a chiral stationary phase; ee calculated from peak area ratio. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, ethyl acetate) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion, offering sub-ppt detection limits and compliance with ICH Q3D. |
| Inorganic Impurities (Sulfate, Chloride, Sulfide) | Ion Chromatography (IC) | Anion exchange separation with conductivity detection for sulfate, chloride, and sulfide species. |
| Related Substances | HPLC-UV/DAD | Detection and quantification of structurally related impurities (e.g., deaminated, oxidized, or dimeric by-products) using gradient HPLC with diode array detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via controlled heating; used for identity confirmation and purity screening (sharp range indicates high purity). |
| Specific Optical Rotation | [α]D | Measurement of plane-polarized light rotation in solution at 589 nm; confirms chiral integrity and batch-to-batch consistency. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Analysis | High-temperature incineration followed by weighing of inorganic residue to assess total inorganic impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine D10, D50, D90 values relevant for formulation handling and dissolution performance. |
