Industrial Applications of DI-BOC-CYSTAMINE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Used as a protecting reagent for cysteine residues to enable selective disulfide bond formation in peptide synthesis | In solid-phase peptide synthesis (SPPS), the Boc protecting group is selectively removed, followed by oxidation to form disulfide bonds; commonly applied in the synthesis of cyclic peptides or protein mimetics containing disulfide bonds |
| Biochemical Research | Used as a reversible disulfide crosslinking agent for studying protein structure and function | The Boc group is cleaved under mild acidic conditions (e.g., TFA/DCM) to liberate free thiol groups, which subsequently form intramolecular or intermolecular disulfide bonds upon exposure to air or oxidants (e.g., I₂, DMSO) |
| Materials Science | Used as a functional crosslinking unit for preparing responsive hydrogels or intelligent drug delivery carriers | Disulfide bonds are incorporated into polymer backbones or side chains; reduction-triggered cleavage (e.g., by intracellular glutathione) induces material degradation or drug release |
Manufacturing Quality Control of DI-BOC-CYSTAMINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by reverse-phase HPLC with UV detection at 210 nm using a calibrated standard curve. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV against reference standards or threshold-based reporting. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, ethyl acetate, toluene) per ICH Q3C. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and dilution. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous solution after sample dissolution and filtration. |
| Residue on Ignition | Gravimetric Analysis | Mass loss measurement after high-temperature ashing (700-800 C) to determine inorganic residue. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to obtain D10, D50, D90 values per ISO 13320. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) to assess acidic/basic degradation products. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and absence testing for specified pathogens per USP <61> and <62>. |
