Manufacturing Quality Control of DISUCCINIMIDYL SUBERATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., mono-NHS ester, hydrolyzed acid) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DMF, THF, acetonitrile) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water via iodine-sulfur dioxide reaction in anhydrous methanol-based medium. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| NHS Ester Content | UV-Vis Spectrophotometry | Quantification of NHS ester group based on absorbance at 260 nm, calibrated against a reference NHS compound or hydrolysis-derived succinimide. |
| Heavy Metals | ICP-OES | Multi-element detection of Pb, Cd, Hg, As, and Ni after microwave-assisted acid digestion and plasma excitation emission measurement. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| Particle Size Distribution | Laser Diffraction | Measurement of dry powder particle size distribution based on angular scattering pattern of laser light through dispersed sample. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection by observing the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Specific Optical Rotation | Polarimetry | Measurement of chiral rotation of plane-polarized light in solution, used to assess enantiomeric purity if applicable. |
| Microbial Contamination | Membrane Filtration | Quantitative enumeration of aerobic mesophilic microorganisms following filtration, membrane transfer, and incubation on TSA agar. |
