Manufacturing Quality Control of DL-BETA-PROLINOL HCL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to measure trace water via stoichiometric reaction with pyridine/methanol buffer. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight; residue mass expressed as percentage of original sample. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion, measuring emission intensities of metal atoms excited in argon plasma. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| pH (1% aqueous solution) | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a 1% w/v aqueous solution at 25 C using calibrated glass electrode. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, used to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP <741>. |
| Organic Volatile Impurities | GC-FID | Headspace or direct injection GC with flame ionization detection to quantify residual solvents per ICH Q3C guidelines. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to determine volume-based particle size distribution in dispersed dry or wet samples. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic microorganisms and absence testing for specified pathogens using standardized culture media and incubation conditions per USP <61> and <62>. |
