Description

7-Mercapto-4-Methylcoumarin is a specialized heterocyclic organic compound belonging to the coumarin family, distinguished by the presence of a reactive thiol (mercapto) group. This unique structure makes it a valuable intermediate for synthesizing advanced materials and functional molecules, particularly in photochemistry and polymer science. It is essential for researchers and manufacturers in the fields of photoinitiators, fluorescent probes, polymer cross-linking agents, and pharmaceutical intermediates.

Application

• Photoinitiator and UV-Curable Resin Component: Acts as a key co-initiator or synergist in free radical polymerization systems for coatings, inks, and adhesives.
• Fluorescent Probe and Sensor Development: Used in the synthesis of chemosensors and bioimaging agents due to its coumarin-based fluorophore.
• Polymer Modification and Cross-linking Agent: The thiol group enables thiol-ene "click" chemistry for modifying polymer chains and creating network structures.
• Pharmaceutical Intermediate: Serves as a building block for the synthesis of more complex molecules with potential biological activity.
• Organic Synthesis Intermediate: Utilized in various organic transformations, including the preparation of thioethers and other sulfur-containing compounds.
• Material Science Research: Employed in the development of novel organic electronic materials and smart polymers.

Quality Control

Our 7-Mercapto-4-Methylcoumarin is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
