相关描述
4,8,12,16,20,24-Hexaoxaheptacosane-1,27-diol (CAS No. 69039-85-6) is a polyether diol featuring a six-oxygen-containing heptane ring structure, with the molecular formula C₂₁H₄₄O₈ and a molecular weight of 424.57. It consists of seven propylene glycol units connected linearly by ether bonds, and bears a primary hydroxyl group at each terminus, endowing it with high reactivity. The compound is typically synthesized via ring-opening polymerization of propylene oxide, using an alkaline catalyst to control polymerization degree, followed by purification to achieve high purity (≥95%). Owing to its excellent hydrophilicity and biocompatibility, it is widely employed in drug delivery systems (e.g., synthesis of PEG-based derivatives), modification of biomedical materials, and the development of long-acting protein therapeutics, making it a key functional intermediate in the biomedical field.
