Decanoic anhydride
Decanoic anhydride (CAS 2082-76-0), also known as capric anhydride, is the symmetrical acid anhydride of decanoic (capric) acid, with the linear formula [CH3(CH2)8CO]2O and a molar mass of 326.51 g/mol. It is a low-melting solid to clear, colourless-to-light-yellow liquid that is soluble in chloroform. Used principally as a decanoylating (acylating) reagent in organic synthesis, it introduces the C10 fatty-acyl group onto hydroxyl and amino functions. Tech Serve Solutions supplies and exports this reagent worldwide.

Decanoylation and O-acylation reagent
Decanoic anhydride introduces the decanoyl (C10) group onto hydroxyl and amino functions, forming esters and amides. It has been used in the synthesis of per-O-decanoylated glycopyranose building blocks such as a tetra-O-decanoyl-D-glucopyranose derivative.
Fatty-acyl building block
As a saturated medium-chain fatty acyl donor, it serves as a building block in the preparation of lipids, glycolipids and other long-chain conjugates where a defined C10 chain is required.
Research and laboratory synthesis
Supplied as a reagent-grade anhydride, it is used in chemical synthesis and method-development work across academic and industrial laboratories for controlled acylation chemistry.
Intermediate for derivatisation
The anhydride can be applied to derivatise alcohols and amines, for example to improve solubility, lipophilicity or analytical handling of polar substrates in synthetic routes.
