Everolimus EP Impurity A-d3
Everolimus EP Impurity A-d3 combines two functions in a single standard: it corresponds to a pharmacopoeial impurity of everolimus, the rapamycin-derived mTOR inhibitor used in transplantation and oncology, and it carries three deuterium atoms that shift its mass away from the unlabelled species. The result is a C51H76D3NO13 molecule of molecular weight 917.19 that can serve both as an impurity marker and as an internal standard within the same analytical run. Analytical groups use it during HPLC or LC-MS method development, for peak identification and system suitability checks, and for quantitative calibration where a labelled counterpart is required. This off-white solid requires storage at -20 °C (±5 °C) and ships with ice packs. Pack sizes include 0.5 mg, 1 mg, 4.5 mg, 5 mg, 10 mg, 25 mg, 50 mg and 100 mg. Requests for quotations or further documentation are welcome.
