Octatriacontanoic acid
chemical compound
Octatriacontanoic acid, or octatriacontylic acid, is a 38-carbon saturated fatty acid with the chemical formula CH3(CH2)36COOH. The acid is rare due to its longer carbon backbone, imparting its special physical and chemical properties.
Synthesis
Synthetic methods
Octatriacontanoic acid can be synthesized via multiple established carboxylic acid preparation techniques. Key approaches include oxidation reactions, where primary alcohols or aldehydes are treated with oxidizing agents such as potassium permanganate (KMnO4) or chromium trioxide (CrO3) to produce the acid.
Industrial production
Commercial synthesis typically employs Grignard reagent carboxylation. This process involves reacting a Grignard reagent with carbon dioxide (CO2) to form a metal carboxylate intermediate, which is subsequently acidified to yield the final carboxylic acid. This method is preferred industrially due to its high efficiency and scalability, enabling cost-effective large-scale production.
Uses
Due to its emollient properties, the compound is used to produce cosmetics and personal care products as a valuable ingredient in lotions and creams. Industrial uses include producing lubricants and surfactants.
Begin with the source’s own compact description: “Octatriacontanoic acid” is chemical compound. The dossier treats that line as a proposition to test through Octatriacontanoic, 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.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 15, 2026. The linked authority identifier is Q27270997. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
