Background:

2,3-dinor Thromboxane B₂-d₉(2,3-dinor TXB₂-d₉) contains 9 deuterium atoms at the 15, 15, 16, 16, 17, 17, 18, 18, and 18 positions. It is intended for use as an internal standard for the quantification of 2,3-dinor TXB₂by GC- or LC-mass spectrometry. TXB₂is released in substantial quantities from aggregating platelets and metabolized during circulation to 11-dehydro TXB₂and 2,3-dinor TXB₂.¹2,3-dinor TXB₂is an abundant urinary metabolite of TXB₂and can be used as a marker forin vivoTXA₂synthesis.^1,2,3In healthy male volunteers, the median excretion of 2,3-dinor TXB₂is 10.3 ng/hour (138 pg/mg creatine).²
