Consider testing any materials in question for peroxide formation. Use peroxide formation test results for data-based use and/or potential disposal determinations. Consider use of XploSensPS or similar product.

Subject: [DCHAS-L] Inquiry on Isoamyl Alcohol as a Peroxide Former
**External Sender**
Dear Colleagues,
Isoamyl alcohol (3-Methyl-1-butanol) is classified as a Class B peroxide former, as confirmed by multiple sources. However, I have yet to find case studies or documented incidents where it has caused issues
beyond its inherent flammability. Given its recent designation as a “green” and renewable chemical, with proposed recycling and bioproduction initiatives, I am interested in understanding how industry currently manages isoamyl alcohol in this context.
If anyone has insights on industry handling practices or case studies where isoamyl alcohol has posed peroxide-related risks, I would greatly appreciate your input. My intent is to use this information to
help establish policies with my colleagues in the bio-based sector.
Thank you for your time and expertise.
Regards,
Tammy Rechtin
