Source-derived summary

1,2-Propanedithiol, sometimes called 1,2-dimercaptopropane, is a thiol with the formula HSCH2CH(SH)CH3. This colorless, intensely odorous liquid is the simplest chiral dithiol. Related dithiols include 1,2-ethanedithiol, 2,3-dimercapto-1-propanesulfonic acid, and 1,3-propanedithiol. It is generated by the addition of H2S to the related episulfide, CH3CHCH2S.

Editorial summary

This brief starts where responsible research should: with the source description of “1,2-Propanedithiol” as chemical compound. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—2011—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where 2-Propanedithiol, chemical and compound can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as chemical compound. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q4545659. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2011.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
