Frequently Asked Questions
What is octylisothiazolinone (OIT) used for?
OIT (2-octyl-2H-isothiazol-3-one, CAS 26530-20-1) is an isothiazolinone biocide used as a film and in-can preservative. Typical uses are paints and coatings, adhesives and polishes, metalworking fluids, and wood and leather preservation. RawSource supplies it in bulk to coatings and preservative formulators.
What is 2-octyl-2H-isothiazol-3-one?
It is an octyl-substituted isothiazolinone (CAS 26530-20-1, C11H19NOS), also called OIT or octhilinone. It functions as a non-metal preservative/biocide for industrial materials, providing dry-film and in-can microbial protection in coatings and related products.
Is OIT the same as DCOIT or other isothiazolinones?
No. OIT (2-octyl, CAS 26530-20-1) is distinct from DCOIT (4,5-dichloro-2-octyl, a separate CAS) and from the CMIT/MIT 3:1 blend. They are different actives with different specifications; confirm identity by CAS number on the CoA when ordering.
How is bulk OIT supplied and quoted?
RawSource supplies OIT in industrial bulk packaging to manufacturers, typically as the active or in a carrier depending on grade. Pricing is volume- and grade-dependent; request a bulk quote with your active-content and packaging needs. CoA and SDS ship with each order.
What UN number and shipping classification apply to OIT?
2-Octyl-3-isothiazolone is assigned UN 2922. It is a regulated material and must be shipped per DOT/IMDG/IATA rules for its packing group; RawSource handles compliant bulk shipment with SDS and CoA. Confirm DOT details with our team before arranging freight.
