Industrial Applications of BOC-D-PYR-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Chemicals | Peptide drug synthesis | As a derivative of D-pyroglutamic acid, used to incorporate D-pyroglutamic acid residues in solid-phase peptide synthesis (SPPS) or solution-phase synthesis for constructing peptide drug molecules with defined stereochemistry. |
| Pharmaceutical Chemicals | Synthesis of pharmaceutical intermediates | As a key chiral building block for synthesizing active pharmaceutical ingredients (APIs) containing the D-pyrrolidone carboxylic acid motif, such as specific antibiotics or peptide-based inhibitors. |
| Research Reagents | Peptide structural studies | Used to synthesize peptide reference standards or model compounds to investigate the effect of D-amino acids on secondary structure features (e.g., folding, stability) of peptide chains. |
| Biotechnology | Protecting group strategy | Leverages the reversible protection of amino groups by the Boc (tert-butoxycarbonyl) group to enable selective deprotection and functionalization in complex organic synthesis routes. |
Manufacturing Quality Control of BOC-D-PYR-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., ethyl acetate, toluene) by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Optical Rotation | [alpha]D | Measures specific rotation using sodium D-line light in a polarimeter to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-OES | Quantifies total heavy metals (Pb, Cd, Hg, As, etc.) after acid digestion by inductively coupled plasma optical emission spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual non-volatile matter. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| pH of Aqueous Solution | Potentiometric Titration | Measures hydrogen ion activity in a saturated aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering pattern of laser beam passing through dispersed sample. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms and specified pathogens (e.g., E. coli, S. aureus) by filtration, culture, and colony enumeration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation of phase change. |
