4,4-Dimethyloxazolidine

4,4-Dimethyloxazolidine (CAS 51200-87-4) is a cyclic oxazolidine compound supplied under trade names including Oxaban A, Oxadine A, Zoldine ZA, and Nuosept 101. It carries no assigned E-code and is classified under HS code 2934999090 within the heterocyclic compounds category.

In metalworking and industrial water treatment, 4,4-dimethyloxazolidine functions as a formaldehyde-releasing biocide, controlling bacterial and fungal growth in recirculating systems and cutting fluid emulsions by disrupting microbial cell membranes. In oil and gas applications, it is incorporated into production chemistry programs where it provides both preservation and corrosion inhibition by scavenging sulfur-reducing bacteria that accelerate metal degradation.

This material is supplied in liquid form and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm SDS compliance and concentration-specific classification prior to formulation, particularly where biocidal product regulations under BPR (EU 528/2012) may apply. Standard packaging includes drums and IBCs.
