Manufacturing Quality Control of BOC-DL-MET-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (BOC-DL-Methionine content) | HPLC with UV detection | Separation on a reversed-phase column followed by quantification using UV absorbance at 210 nm against a reference standard. |
| Optical Purity (Enantiomeric Excess) | Chiral HPLC | Separation of D- and L-enantiomers using a chiral stationary phase; enantiomeric excess calculated from peak area ratio. |
| Loss on Drying | Gravimetric thermogravimetry | Mass loss measured after drying at 105 C for 2 hours under atmospheric pressure. |
| Residue on Ignition | Sulfated ash gravimetry | Mass of inorganic residue remaining after controlled combustion at 700-800 C. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals following acid digestion and plasma excitation/emission spectroscopy. |
| Chloride Impurity | Potentiometric titration with AgNO3 | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change. |
| Sulfate Impurity | Turbidimetric assay | Reaction with barium chloride under acidic conditions to form BaSO4 precipitate; quantified by light scattering. |
| Related Substances | HPLC with gradient elution | Separation and quantification of impurities (e.g., BOC-glycine, DL-methionine, des-BOC product) using UV detection. |
| Water Content | Karl Fischer titration | Volumetric or coulometric determination based on stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| pH of 1% Aqueous Solution | Potentiometric pH measurement | Measurement using calibrated glass electrode in a 10 mg/mL aqueous suspension after equilibration. |
| Specific Optical Rotation | [a]D | Measurement of rotation angle of plane-polarized light at 589 nm using a digital polarimeter; reported per dm and g/mL. |
| Microbial Limits | Membrane filtration and plate count | Enumeration of aerobic mesophilic bacteria and molds/yeasts after filtration, membrane transfer, and incubation on appropriate agar media. |
