Question # 538

538. A covered facility uses a toxic chemical known to them as DOP, which they think is n-dioctyl phthalate. N-dioctyl phthalate has the CAS number 117-84-0 and is not on the Section 313 list. However, the SDS from their supplier states that the toxic chemical is called DEHP or DOP and has the CAS number 117-81-7. DEHP is di(2-ethylhexyl) phthalate on the Section 313 list. Should this chemical be reported?
DOP is a commonly used acronym for both di(2-ethylhexyl) phthalate (DEHP) and n-dioctyl phthalate (DNOP). DOP is also listed as a synonym for DEHP in the Section 313 Common Synonyms document. However, as the supplier provided the acronym DEHP and the CAS number is 117-81-7, the facility has sufficient information to distinguish between DNOP and DEHP and thus should report for DEHP.
