Long-Chain Diacids & Mono-Protected Diacids

Long-chain dicarboxylic acids (diacids) are bifunctional monomers with carboxylic acid groups at both ends of an aliphatic chain. Their ester derivatives — dimethyl, monomethyl, and mono-tert-butyl — serve as protected intermediates for selective polymerization and step-growth synthesis. MONOPOLY offers the full C-14 through C-22 homologous series in all four forms.

Long-Chain Omega-Amino Acids

Omega-amino acids are bifunctional monomers carrying both an amine (–NH₂) and a carboxylic acid (–COOH) at opposite ends of a long aliphatic chain. They are key building blocks for polyamides (nylons), polyurethanes, and specialty coatings, enabling precise control over chain length, crystallinity, and thermal performance. MONOPOLY offers the full C-12 through C-22 homologous series.
