§ 721.1240 Benzene, (2-bromoethyl)-, ar-bromo derivatives.

(a) Chemical substance and significant new uses subject to reporting. (1) The chemical substance identified as benzene, (2-bromoethyl)-, ar-bromo derivatives (PMN P-84-704; CAS No. 125904-10-1) is subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section. The requirements of this SNUR do not apply when the substance is present only in a mixture or in a polymer matrix, if the combined concentration of this substance and the substance identified in § 721.1230 as benzene, ethenyl-, ar-bromo derivatives (PMN P-84-660; CAS No.125904-11-2) present as residual monomers in the mixture or polymer matrix, does not exceed 0.5% by weight or volume. This exemption does not apply if there is reason to believe that during intended use, processing, or other handling, these substances combined may be reconcentrated above the 0.5% level in the mixture or polymer matrix.
