Thromboxane B2-d9 (TXB2-d9) is intended for use as an internal standard for the quantification of TXB2 (Item No. 19030) by GC- or LC-MS. TXB2 is a stable, biologically inert metabolite formed from the non-enzymatic hydrolysis of TXA2, which has a half-life of about 30 seconds.{488} Urinary analysis of TXB2 accurately reflects intrarenal TXA2 synthesis, while measurement of 11-dehydro and 2,3-dinor thromboxane metabolites gives the best estimate of systemic TXA2 secretion.{6304,717,868}
