| Chemical synthesis | Heterobifunctional crosslinker intermediate | Features a carboxylic acid group amenable to activation and esterification at one end, and a maleimide group for selective thiol coupling at the other end |
| Analytical chemistry | Biomolecular probe labeling | Labels thiol-containing peptides, proteins, or nucleic acid aptamers with fluorescent or isotopic tags |
Manufacturing Quality Control of 6-Maleimidocaproic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 254 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 relative to reference standards. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., DMF, acetone) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration | Neutralization of acidic functional groups with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Heavy Metals | ICP-OES | Multi-element quantification of metal impurities (e.g., Pb, Cd, Ni) after acid digestion, based on element-specific atomic emission intensities. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing (500-600 C) and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs, using calibrated capillary method. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity using calibrated glass electrode and reference electrode in aqueous suspension. |
| Microbial Contamination | Membrane Filtration | Enumeration of aerobic microorganisms by filtration, membrane transfer to culture media, and colony counting after incubation. |
