7-Methyloctanoic acid

7-Methyloctanoic acid (CAS 693-19-6), also known commercially as isopelargonic acid, is a branched-chain fatty acid used across industrial formulation chemistry.

Its branched structure resists oxidation and crystallization, making it a preferred building block for esters, metallic soaps, and specialty intermediates where straight-chain acids underperform.

In lubricants and metalworking fluids, it functions as a corrosion inhibitor and lubricity additive, particularly in formulations requiring oxidative stability under high-temperature conditions.

Personal care manufacturers use it to produce ester derivatives, such as isononyl esters, that deliver lightweight emolliency in skin and hair products for various applications.

In plastics and polymer processing, it serves as a precursor to plasticizers and metal soap stabilizers that improve flexibility and processing behavior in PVC and related systems.

Coatings and adhesive formulators incorporate its metallic salt forms as driers or adhesion-promoting components in solvent-borne systems to enhance overall product performance.

7-Methyloctanoic acid is supplied as a clear to pale yellow liquid. Technical grade is the standard commercial offering, with purity typically specified at 98% or higher.

Packaging ranges from drums to IBC containers, with bulk availability depending on supplier requirements. This material is handled according to standard industrial safety protocols.
