I don't know how a diol on a straight-chain sugar is supposed to form a 5-membered heteroatom ring . . . basically the alcohol oxygens are geminal ethoxy atoms on a propyl chain, ( but vicinal diols on the sugar chain ) . . . talk ) 18 : 22, 6 November 2009 ( UTC)

All the various hydrogels have different advantages and disadvantage, such as biocompatibility, protein stability, toxicity, or lifetime; for example, the gelling conditions for sol-gels may damage the protein, and, as a result, several copolymers, such as chitosan, may be added ( making hybrid gels ) or alternative monomers, such as glycol-modified tetraethoxysilane as it is more biocompatible than the commonly used methoxy-or ethoxy-modified tetraethoxysilane.

"' 2CD-5EtO "'is a psychedelic phenethylamine 2C-D, where the 5-methoxy group of 2C-D has been lengthened to an ethoxy group . 2CD-5EtO is a representative example of the so-called " tweetio " compounds discovered by Alexander Shulgin and briefly mentioned in his book PiHKAL, which are homologues of the 2C family of drugs, where either one or both of the methoxy groups at the 2, 5-positions of the aromatic ring have been replaced by ethoxy.

A large number of tweetio derivatives of various 2C drugs have been synthesised and tested, including the 2-ethoxy homologues 2CD-2EtO, 2CB-2EtO, 2CI-2EtO, 2CT-2EtO, 2CT2-2EtO, 2CT4-2EtO and 2CT7-2EtO, the 5-ethoxy homologues 2CD-5EtO, 2CE-5EtO, 2CB-5EtO, 2CT-5EtO and 2CT2-5EtO, and the 2, 5-diethoxy homologues 2CD-diEtO, 2CB-diEtO and 2CT2-diEtO . In general the 2-ethoxy homologues were all several times less potent and somewhat shorter acting than the parent compounds, while the 2, 5-diethoxy homologues were far less potent and qualitatively milder even at high doses.
