Thidiazuron

C9H8N4OS, 220.257 g/mol. Its structure, the values that were measured, the values that were calculated, and where each one came from.

Measured properties

Values somebody obtained from a sample and published. Where two sources report the same property they are both shown, in the units each used — a disagreement between them is information, and averaging it away would be inventing a number neither one gave.

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

  • Amide

    A carbonyl bonded directly to nitrogen.

  • 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.

Reactions it appears in

No documented reaction with a written procedure and a source involves Thidiazuron yet.

Other names for it

No systematic name is recorded.

The sources also call it 1-Phenyl-3-(1,2,3-thiadiazol-5-yl)urea, Defolit, Dropp, 1-phenyl-3-(thiadiazol-5-yl)urea, N-Phenyl-N'-1,2,3-thiadiazol-5-ylurea, (N-1,2,3-Thiadiazolyl-5)-N'-phenylurea, N'-phenyl-N-(1,2,3-thiadiazol-5-yl)carbamimidic acid, Urea, N-phenyl-N'-1,2,3-thiadiazol-5-yl-, 5-Phenylcarbamoylamino-1,2,3-thiadiazole, (phenylamino)-N-(1,2,3-thiadiazol-5-yl)carboxamide, Thidiauron, Avguron.

Seen alongside it in reaction records

Molecules that appear in the same recorded reactions as Thidiazuron. 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

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.
