FAQ
Frequently asked questions
What makes Isononanoic Acid different from 2-EHA?
Isononanoic acid has a branched C9 structure (mainly 3,5,5-Trimethylhexanoic acid) offering superior thermal and oxidative stability compared to the linear C8 2-EHA. This makes INA preferred for high-temperature lubricant esters and demanding coating applications.
What is the typical purity of your Isononanoic Acid?
Our INA delivers 3,5,5-Trimethylhexanoic acid content above 99.5%, ensuring consistent performance in downstream synthesis and formulation.
Is Isononanoic Acid compatible with metalworking fluid formulations?
Yes, INA-derived esters serve as excellent corrosion inhibitors in metalworking coolants and provide superior lubricity compared to conventional alternatives.
