Description
Bansyl Chloride is a specialized organic reagent primarily used as a derivatization agent for analytical chemistry and as a key intermediate in fine chemical synthesis. Its high reactivity makes it an essential tool for modifying compounds to enhance their detectability or to introduce specific functional groups. This product is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and analytical laboratory sectors who require precise and reliable building blocks for advanced synthesis and analysis.
Application
- Derivatization Agent for HPLC Analysis: Used to tag amines, amino acids, and other nucleophiles to improve their UV or fluorescence detection.
- Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs) and complex drug molecules.
- Proteomics Research: Employed in peptide sequencing and protein labeling studies due to its selective reactivity.
- Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides.
- Dye and Pigment Intermediate: Acts as a precursor in the manufacture of specialized dyes and functional colorants.
- Cross-linking Reagent: Utilized in polymer chemistry and material science to create modified surfaces or cross-linked networks.

Quality Control
Our Bansyl Chloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality management system is designed to meet the rigorous demands of research and industrial synthesis applications.
Storage
Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
