Neodecanoic Acid (CAS No. 26896-20-8), also known as Versatic Acid 10, is a synthetic carboxylic acid with a highly branched-C10 tertiary carboxylic acid. it is not a single compound but a mixture of isomers, each sharing the general formula C₁₀H₂₀O₂.  The key to understanding its behavior lies in its branched-chain structure. This is unlike straight-chain carboxylic acids, impacting its reactivity and physical properties. The branched structure is responsible for its relatively low vapor pressure, a crucial factor in its industrial appeal. Lower vapor pressure translates to easier handling, reduced risk of volatile emissions, and enhanced safety in industrial settings. Its unique combination of properties—such as hydrophobicity, UV stability, and high reactivity—makes it a valuable component in adhesives, lubricants, coatings, and more. Novacid NEO10 can be replacement of Versatic Acid 10.

This branched structure also influences the acid's behavior in reactions. Its behavior is similar to that of trialkyl acetic acids, a class known for their steric hindrance related to its branched alkyl groups. This steric hindrance might affect reaction rates and selectivity in certain chemical processes, making NDA suitable for specific synthetic pathways where precise control is necessary. (R1 and R2 are alkyl groups. Novacid NEO10 contains a total of 10 Carbon atoms. Novacid NEO10 is a water-like clear product hat is liquid at ambient temperature.)

Novacid NEO10 is a key intermediate in the manufacture of a variety of products, which typically show excellent hydrolyic stabilliy and resistance to various chemical agents. This is due to the steric hindrance created by the highly branched Versatic structure combined with the tertiary nature of its alpha-carbon atom. This is especially demonstrated in comparison with its linear and secondary-C10 equivalents.
Novacid NEO10 can be used in its acid form, but for many applications the product is typically first converted into an acid chloride or metal salt. The acid chloride is produced by reaction with, for exampie, phosgene or PClʒ and is used in the production of peroxides for polymer production.Metal salts,e.g. Cobalt, Copper or Zinc salts of Novacid NEO10 are used in applications such as tire adhesives, paint driers, PVC heat stabilisers, chemical processing catalysts, unsaturated polyester cure catalysts, wood preservatives and fuel additives. Additionally, Novacid NEO10 is a very effective metal extraction agent that is particularly suitable for Nickel. The acid can also be used as corrosion inhibitor in synthetic lubricants.
