Manufacturing Quality Control of H-PHE-PHE-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies L-Phe-L-Phe content using reversed-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Optical Rotation | [alpha]D | Measures specific optical rotation in aqueous solution using a polarimeter to confirm chiral integrity and enantiomeric purity. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., mono-Phe, diketopiperazine, hydrolysis products) via gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Determines trace organic solvents (e.g., methanol, ethyl acetate, toluene) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Quantifies toxic elements (Pb, Cd, As, Hg, Ni) at sub-ppb levels by inductively coupled plasma mass spectrometry after acid digestion. |
| Water Content | Karl Fischer Titration | Determines total water content volumetrically or coulometrically using iodine-based redox titration in anhydrous methanol medium. |
| pH (1% w/v aqueous solution) | pH Meter | Measures hydrogen ion activity in a standardized aqueous solution using a calibrated pH electrode system. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C followed by precise weighing of the residual residue. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic mesophilic microorganisms and detects specified pathogens (E. coli, Salmonella) per USP <61> and <62>. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dry powder form using Mie scattering theory and laser diffraction instrumentation. |
| Loss on Drying | Thermogravimetric Analysis | Determines volatile matter loss by heating sample at 105 C under controlled conditions and measuring weight change. |
| Chiral Purity | Chiral HPLC | Separates and quantifies enantiomeric impurities using a chiral stationary phase HPLC column with UV detection. |
