Manufacturing Quality Control of 4-Nitrophenyl beta-D-galactopyranoside
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorbance at 300-400 nm using reversed-phase C18 column and calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., nitrophenol, galactose derivatives) via gradient elution and peak area comparison. |
| Water Content | Karl Fischer Titration | Measures trace water by iodometric titration where water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual non-volatile matter. |
| Heavy Metals | ICP-OES | Quantifies metal contaminants (e.g., Pb, Cd, Ni, Fe) by plasma excitation and elemental emission wavelength detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures sulfate-derived inorganic residue after ignition with sulfuric acid treatment and subsequent weighing. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring rotation angle of plane-polarized light passing through a solution at specified concentration and temperature. |
| pH of Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in aqueous suspension using calibrated glass electrode and reference electrode. |
| Solvent Residues | GC-FID | Identifies and quantifies residual solvents (e.g., methanol, acetone, ethyl acetate) using capillary column separation and flame ionization detection. |
| Microbial Contamination | Membrane Filtration | Detects viable aerobic microorganisms by filtration, membrane transfer to nutrient agar, and colony enumeration after incubation. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or dispersed particle size distribution based on angular scattering pattern of laser beam passing through sample. |
