Octadecanedioic Acid Mono-tert-butyl Ester (CAS 843666-40-0)

Octadecanedioic Acid Mono-tert-butyl Ester, also known as 18-(tert-Butoxy)-18-oxooctadecanoic Acid and Boc-C16-COOH, is a mono-tert-butyl-protected long-chain dicarboxylic acid derivative used as a building block in peptide side-chain synthesis and related conjugation research.

Shandong Juntai Pharmaceutical supplies this product with a purity specification of ≥99.0%, supported by quality control covering identification, purity, related substances, residual solvents, water content and assay.

Product Information

What Is Octadecanedioic Acid Mono-tert-butyl Ester?

Octadecanedioic Acid Mono-tert-butyl Ester is a mono-protected derivative of octadecanedioic acid.

Its molecular structure contains one free carboxylic acid group and one carboxyl group protected as a tert-butyl ester. This differentiated functional-group arrangement allows the molecule to participate in stepwise coupling and deprotection during the construction of long-chain side-chain and linker structures.

The compound is therefore used as a synthetic building block in peptide-related and conjugation chemistry.

Applications in Peptide Side-Chain Synthesis

CAS 843666-40-0 can be used as a long-chain dicarboxylic acid building block in peptide side-chain synthesis, lipidation-related research and other conjugation processes requiring a protected long-chain carboxylic acid structure.

The free carboxylic acid group can participate in further coupling reactions, while the tert-butyl-protected terminus provides a protected functional group for subsequent synthetic steps.
