What is Nonanoic acid?
Nonanoic acid (CAS 112-05-0), also known as pelargonic acid, is a nine-carbon saturated fatty acid derived primarily from oleic acid oxidation.
Where is Nonanoic acid used?
- Lubricant and metalworking: precursor to nonanoate ester base fluids
- Corrosion inhibitors in cutting oils and hydraulic fluids
- Personal care: emulsified skin and hair products
- Food and beverage: FEMA 2784 flavoring agent for fruit and dairy profiles
- Specialty chemical synthesis: catalyst intermediate and pH buffer
- It functions as a pH regulator and emulsifier.
Good to know: Buyers sourcing for flavor applications should confirm FEMA compliance. Food-grade and technical-grade designations are the most common commercial specifications.
Commercial specifications
- Technical-grade material with defined acid value and purity thresholds
- Bulk and intermediate packaging formats
