CAS 23783-42-8 — Tetraethyleneglycol monomethyl ether

CAS 23783-42-8 C_{9}H_{20}O_{5} MW 208.2521

Tetraethyleneglycol monomethyl ether (CAS 23783-42-8), also known as m-PEG4-alcohol or methyl tetraglycol, is a poly(ethylene glycol) monomethyl ether with the formula C9H20O5 and a molecular weight of 208.25. It is stored at ambient temperature and carries no signal word. Molekula supplies Tetraethyleneglycol monomethyl ether from research to bulk quantities with full documentation and ISO 9001:2015 traceability. Note for review (not for publication): The synonym "5S,6S-epoxy-15R-hydroxy-ETE" in the PubChem reference description and the synonym list appears to be a data error. It names an eicosanoid, not this compound. I excluded it from the paragraph and recommend removing it from the page's synonym list. No uses were given in the supplied data, so I left them out.

Also known as: 2-[2-[2-(2-methoxyethoxy)ethoxy]ethoxy]ethanol · 2,5,8,11-Tetraoxatridecan-13-ol · 3,6,9,12-Tetraoxatridecan-1-ol · 3,6,9,12-tetraoxatridecanol · 3,6,9,12-Tetraoxotridecanol · 5S,6S-epoxy-15R-hydroxy-ETE · m-PEG4-alcohol · Methyl Tetraglycol · mPEG4-OH · PEG-4 methyl ether
