Manufacturing Quality Control of N-ME-4-METHOXY-PHE-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-220 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3A/B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common solvents (e.g., methanol, dichloromethane, ethyl acetate) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As, Ni) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential jump due to AgCl precipitation. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using a polarimeter at 20 C and sodium D-line (589 nm), confirming stereochemical integrity and enantiomeric purity. |
| Residue on Ignition | Gravimetric Analysis | Ignition at 700-800 C followed by weighing of non-volatile inorganic residue to assess inorganic ash content. |
| pH (1% aqueous solution) | pH Meter | Direct measurement using calibrated pH electrode in a 1% w/v aqueous solution at 25 C to verify acid salt consistency. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using laser diffraction to determine D10, D50, D90 values per USP <429>. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic mesophilic microorganisms and absence testing for specified pathogens (e.g., E. coli, S. aureus) per USP <61> and <62>. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs, verifying identity and crystallinity per USP <741>. |
