Manufacturing Quality Control of 114676-59-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210 nm, relative to a certified reference standard. |
| Chiral Purity | (R,R)-Enantiomeric Excess | Chiral HPLC with chiral stationary phase (e.g., Chirobiotic T) and UV detection; separates (2R,4R) from other stereoisomers. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., diastereomers, hydrolysis products) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Quantifies residual methanol, ethyl acetate, or dichloromethane by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol medium. |
| Heavy Metals | ICP-OES | Determines total heavy metal content (Pb, Cd, Ni, Cu, Fe) after acid digestion by optical emission spectroscopy. |
| Chloride Content | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant with silver/silver chloride indicator electrode. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash residue after high-temperature incineration at 700-800 C and subsequent weighing. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid material against established visual standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Microbial Contamination | Membrane Filtration | Quantifies aerobic microorganisms via filtration, membrane transfer to agar media, and colony enumeration after incubation. |
