1,8-Octanediol, also known as octamethylene glycol, is a diol with the molecular formula HO(CH2)8OH, a white solid. It can be produced with high purity by hydrogenation of esters of suberic acid.[2]Template:Rp
1,8-Octanediol, which has a low melting temperature, can be found at high purity for relatively low cost. These characteristics are ideal for a reference material at moderate temperature in the context of solid-liquid Phase-Changing Materials (PCMs).[3]
1,8-Octanediol dihexanoate strongly attracts adult male Parallelostethus attenuatus click beetles, and the pheromone of this species may consist entirely of this compound.[4]
Applications
Cosmetics
It is sometimes an ingredient of cosmetics as a plasticizer.[5]
As with other fatty alcohols, octane-1,8-diol is used in cosmetics as an emollient and humectant.Script error: No such module "Unsubst".
Polymers
1,8-Octanediol is used as a monomer in the synthesis of some polymers such as polyesters[6] and polyurethanes.Script error: No such module "Unsubst".
For example, poly(octanediol-co-citrate) is a biodegradable polymer that can be made antibacterial for biomedical applications.[7] This polymer, abbreviated POC[8][9] and also sometimes called poly(octamethylene-citrate),[9] is promising as a biocompatible and biodegradable polymer, and has been extensively investigated in relation to soft tissue engineering.[8]
A polymer created from 1,8-octanediol, citric acid, and sebacic acid, called polyoctanediol citrate/sebacate [p(OCS)], has also been synthesized.[10]
Synthesis
It can also be used in the synthesis of PCE.[11]
