Orthoacetic acid
chemical compound
Orthoacetic acid or ethane-1,1,1-triol is an hypothetical organic compound with formula C2H6O3 or H3C-C(OH)3. It would be an ortho acid with the ethane backbone.
Orthoacetic acid is believed to be impossible to isolate, since it would readily decompose into acetic acid and water. It may have a fleeting existence in aqueous solutions of acetic acid.
Orthoacetate anions
The three hydroxyls of CH3C(OH)3 could be deprotonated, leading successively to CH3C(OH)2(O–) (dihydrogenorthoacetate), CH3C(OH)(O–)2 (hydrogenorthoacetate), and finally CH3C(O–)3 (orthoacetate).
Orthoacetate esters
There are many stable organic compounds with the trivalent moiety H3CC(OR)3, which are formally esters of orthoacetic acid and called orthoacetates. They include trimethyl orthoacetate and triethyl orthoacetate, which are commercially available.
Begin with the source’s own compact description: “Orthoacetic acid” is chemical compound. The dossier treats that line as a proposition to test through Orthoacetic, acid and chemical, not as a finished interpretation.
Why this record matters
The phrase “chemical compound” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 15, 2025. The linked authority identifier is Q7104402. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
