The molecule in three dimensions

Rotate and inspect the atoms. Loaded only when you ask, so the page stays light.

The drawing above is a diagram of what is bonded to what. A molecule is not flat, and the model here is one low-energy shape generated from the connectivity — useful for seeing which groups can reach each other, and not a measured structure. A real sample is a population of conformations, interconverting.

Reactions it appears in

Structurally related

Molecules sharing this formula, or whose fingerprint is at least 40% similar to this one. Similarity is Tanimoto on Morgan fingerprints over this library only — it is a measure of structural overlap, not of how alike they behave.

Seen alongside it in reaction records

Molecules that appear in the same recorded reactions as Diethylene Glycol Monomethyl Ether. This says nothing about structure: most of them are the bases, solvents, ligands and catalysts the chemistry needed, and they are here because somebody put them in the same flask.

What this page does not claim

Identifiers are copied from the source record, measured values are reported as published, and calculated values are marked as calculated. Nothing here is a hazard, purity or handling assessment — how the library is checked.
