Industrial Applications of BOC-CIT-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Protecting reagent for citrulline residues in peptide synthesis | Used as an α-amino protecting group for L-citrulline in solid-phase peptide synthesis (SPPS); the Boc group is selectively removed under acidic conditions (e.g., TFA) to enable controlled coupling |
| Biochemical Research | Preparation of structurally defined citrullinated peptide probes or reference standards | Employed in solution-phase peptide synthesis or fragment condensation to introduce site-specific citrulline modifications, supporting studies of protein arginine deiminase (PAD) activity |
| Diagnostics Reagent Development | Synthesis of antigens for anti-citrullinated protein antibody (ACPA) detection | Conjugated to carrier proteins (e.g., KLH, BSA) to prepare synthetic antigens for in vitro diagnostic kits targeting autoimmune diseases such as rheumatoid arthritis |
Manufacturing Quality Control of BOC-CIT-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Chiral Purity | Chiral HPLC | Separation of enantiomers on a chiral stationary phase; L-isomer content determined by relative peak area. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to determine water via stoichiometric reaction. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents. |
| Heavy Metals | ICP-OES | Multi-element quantification of metal impurities after acid digestion, based on atomic emission intensities. |
| Residual Chloride | Ion Chromatography | Separation and quantification of chloride anions using anion-exchange column and conductivity detection. |
| Related Substances | HPLC-UV | Detection and quantification of structurally similar impurities using gradient reversed-phase HPLC. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under controlled temperature and vacuum to determine volatile content. |
| pH of Solution | Potentiometric pH Measurement | Hydrogen ion activity measured using calibrated glass electrode in aqueous suspension or solution. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine size distribution of solid particles in suspension. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms after filtration, membrane transfer, and incubation on nutrient agar. |
