| Cosmetics | Skin repair and moisturization | Incorporated as an active ingredient |
| Fine Chemicals | Synthesis of fine chemicals | Used as an intermediate or catalyst |
Manufacturing Quality Control of DL-ALANINE-OBZL P-TOSYLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Chiral Purity (Enantiomeric Excess) | Chiral HPLC with UV detection | Separation of DL-diastereomers or enantiomers on a chiral stationary phase; ee calculated from relative peak areas. |
| Residual Solvents (e.g., Benzyl alcohol, Toluene, Methanol) | GC-FID or GC-MS | Volatile organic impurities quantified by gas chromatographic separation and flame ionization or mass spectrometric detection. |
| Water Content | Karl Fischer Titration (coulometric or volumetric) | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol-based medium. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES | Elemental quantification after acid digestion via plasma-induced atomic emission or mass spectrometric detection. |
| Residual Palladium (if catalytically hydrogenated) | ICP-MS | Ultra-trace quantification of Pd following microwave-assisted acid digestion and isotopic dilution or external calibration. |
| Related Substances (Impurity Profile) | HPLC with UV detection | Identification and quantification of structurally related impurities (e.g., DL-phenylalanine benzyl ester, toluenesulfonic acid, free DL-alanine) using gradient elution. |
| Loss on Drying (LOD) | Gravimetric Thermogravimetry | Mass loss measured after controlled heating under specified temperature/vacuum conditions, reflecting volatile content. |
| Specific Optical Rotation | [α]D | Measurement of rotation angle of plane-polarized light at 589 nm to confirm absence of net optical activity (expected near zero for DL-racemate). |
| pH of Aqueous Suspension (1% w/v) | Potentiometric pH measurement | Determination of surface acidity/basicity using calibrated pH electrode in aqueous suspension, indicating residual acidic/basic impurities. |
| Sulfonate Counterion Content | Ion Chromatography (IC) with conductivity detection | Quantification of p-toluenesulfonate anion via suppressed conductivity detection after anion-exchange separation. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as function of angle to determine volume-based particle size distribution in dispersed state. |
| Microbial Limits | Membrane Filtration + Culture Enumeration | Detection and enumeration of aerobic microorganisms per pharmacopeial methods (e.g., USP <61>), if applicable for pharma-grade material. |
