Isononanoic Acid
High-Purity Branched C9 Acid for Lubricants, Coatings and Metalworking Fluids
CAS 3302-10-1
Isononanoic Acid (INA) is a branched C9 carboxylic acid used in polyol ester lubricants, metalworking and coolant systems, paint driers, alkyd resins, and specialty chemical intermediates.
Why Isononanoic Acid
- High-purity branched C9 acid for lubricant ester synthesis
- Low color and low moisture profile support formulation consistency
- Suitable for paint driers, coolants, alkyd resins, acid chlorides, and cosmetic intermediates

FAQ
Frequently asked questions
What makes Isononanoic Acid different from 2-EHA?
INA is a C9 branched acid, while 2-EHA is a C8 branched acid. INA is used in lubricant ester, coating, and industrial-intermediate applications.
What is the typical purity of your Isononanoic Acid?
Isononanoic Acid has a purity of at least 99.5 wt% and an acid value of at least 350 mg KOH/g.
Is Isononanoic Acid compatible with metalworking fluid formulations?
INA-derived esters are used in metalworking coolant and lubricant formulations where corrosion inhibition and lubricity are required.
