2Oethyl

2Oethyl is not a standard chemical name. In chemical nomenclature, this string does not unambiguously define a single compound and is likely to result from typographical error or shorthand for several different possibilities. The most common interpretations are:

- 2-O-ethyl: an ethoxy group (–O–CH2CH3) linked to the second atom (often a carbon) of a larger molecule. This form is encountered in carbohydrate chemistry, where sugar hydroxyls are protected by forming 2-O-ethyl ethers among others, or in general when an ethyl group is bonded through an oxygen to a ring or chain.

- 2-ethoxyethyl: a two-carbon chain bearing an ethoxy substituent, used as a substituent in organic synthesis or as part of protecting groups, for example as part of ethereal linkages that can be cleaved under certain conditions.

- A possible mis-spelling of 2-ethyl, indicating an ethyl substituent at position 2 of a parent molecule.

Because several distinct structures could be described by a similar string, disambiguation requires context: the full parent name, a structural diagram, SMILES notation, or InChI. When encountering 2Oethyl in literature or databases, it is advisable to search for standardized variants such as 2-O-ethyl, 2-ethoxyethyl, or simply 2-ethyl, and verify with structural data.
