Product Overview
15-Crown-5, chemically known as 1,4,7,10,13-pentaoxacyclopentadecane, represents a critical class of crown ethers utilized extensively in modern organic synthesis and chemical research. As a cyclic polyether, this compound exhibits exceptional selectivity for complexing alkali metal cations, particularly sodium ions, due to the specific size match between its central cavity and the ionic radius of the metal. This unique structural property makes it an indispensable reagent for facilitating phase transfer catalysis, enhancing reaction rates, and improving yields in nucleophilic substitution reactions.
Our manufacturing facility produces 15-Crown-5 under stringent quality control protocols to ensure consistent performance in sensitive chemical applications. The product is supplied as a colorless to light yellow transparent liquid, reflecting high levels of purification suitable for both laboratory-scale research and large-scale industrial manufacturing processes. We prioritize safety and compliance, ensuring that all batches meet international standards for chemical intermediates.
