Industrial Applications of (S)-(-)-ALPHA-AMINO-GAMMA-BUTYROLACTONE HYDROBROMIDE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Chiral synthon for pharmaceutical intermediates, particularly in the synthesis of antibiotics and bioactive molecules | Building block in organic synthesis; the homoserine lactone moiety is introduced via alkylation, acylation, and related reactions |
| Research | Used in biochemical studies to mimic or inhibit bacterial quorum-sensing signaling molecules (e.g., acyl homoserine lactones) | Employed as a reference standard or probe at laboratory scale; activity assessed through in vitro bioassays |
| Cosmetics | Potential active ingredient for modulating the skin microbiome (research stage) | Added in trace amounts to formulations to evaluate quorum-sensing interference properties, typically incorporated via emulsification or dissolution |
| Agriculture | Investigational material for inhibiting quorum sensing in plant-pathogenic bacteria (experimental use) | Applied in crop protection trials via spray or irrigation systems to disrupt bacterial pathogenicity |
Manufacturing Quality Control of (S)-(-)-ALPHA-AMINO-GAMMA-BUTYROLACTONE HYDROBROMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 205 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC-UV; identification and quantification based on relative retention times and response factors. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying sample at 105 C for 2 hours under vacuum; reflects volatile content including residual solvents and moisture. |
| Residual Solvents | GC-FID | Detection and quantification of common organic solvents (e.g., methanol, ethyl acetate) using gas chromatography with flame ionization detection. |
| Heavy Metals (as Pb) | AAS | Total heavy metals determined by atomic absorption spectroscopy after acid digestion; reported as lead equivalent. |
| Chloride Impurity | Potentiometric Titration | Quantification of chloride ions using silver nitrate titrant with silver indicator electrode; endpoint detected by potential change. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 under acidic conditions, followed by filtration, drying, and weighing. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric determination of water via iodine-sulfur dioxide reaction in anhydrous methanol-based reagent. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light (589 nm) in solution to confirm chiral integrity and enantiomeric purity. |
| pH of Solution | pH Meter | Measurement of aqueous solution (1% w/v) at 25 C using calibrated glass electrode pH meter. |
| Residue on Ignition | Gravimetric Ashing | Mass of non-volatile inorganic residue after incineration at 600 C for 30 minutes; indicates inorganic ash content. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic mesophilic microorganisms and absence testing for specified pathogens per USP <61> and <62>. |
