C12H17N5O4S, 327.366 g/mol. Its structure, the values that were measured, the values that were calculated, and where each one came from.

Organic — aromatic alcohol

Drawn from the SMILES. It shows how the atoms are connected — not a photograph of a molecule, and not its shape in space.

Calculated properties

Derived from the structure rather than from a sample. These are reproducible and they are not measurements: a calculated partition coefficient and a measured one can differ by a long way, and where both exist they are listed apart on purpose.

Functional groups

Alcohol
An –OH group on a saturated carbon.
Ether
An oxygen bridging two carbons.
Primary aromatic amine
An –NH2 group attached directly to an aromatic ring, as in aniline. Much less basic than an alkyl amine, because the lone pair is delocalised into the ring.
Aromatic ring
A flat six-membered ring with delocalised electrons.
Aromatic ring (five-membered)
A flat five-membered ring with delocalised electrons, such as furan, thiophene or pyrrole.

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.

What this page does not claim

The identifiers are what the source record holds, copied rather than recomputed. Measured values are reported as their source gave them, units and all; calculated values are marked as calculated and are not measurements. Where a field is absent the page says so, because a blank cell reads as a zero and a guessed value reads as a fact.

Nothing here is a hazard assessment, a purity statement or advice about handling a sample. A flash point quoted from a safety database is a number somebody published, not a judgement by us about whether this molecule is safe for what you intend.
