Celecoxib-d₇ is intended for use as an internal standard for the quantification of celecoxib by GC- or LC-MS. Celecoxib is a selective inhibitor of COX-2 (IC₅₀s = 22.9 and 0.05 μM for COX-1 and COX-2, respectively). It displays chemopreventive activity in multiple tumor types via proapoptotic effects that are independent of COX-2 inhibition. Formulations containing celecoxib have been used in the treatment of inflammation while circumventing the gastrointestinal toxicity associated with traditional non-sterodial anti-inflammatory drugs, however, the use of celecoxib has been tempered due to its ability to induce adverse cardiovascular events.

Celecoxib-d7 is the labeled analogue of Celecoxib (C251000), a selective cyclooxygenase-2 (COX-2) inhibitor. Anti-inflammatory. Used in treatment of familial adenomatous polyposis.
