An internal standard for the quantification of temozolomide
Temozolomide-d3 (TMZ-d3) contains three deuterium atoms located on the methyl group. It is intended for use as an internal standard for the quantification of temozolomide by GC- or LC-MS. TMZ is an imidazotetrazine that is converted to a compound capable of alkylating DNA, thus interfering with DNA replication and leading to cytotoxicity in proliferating cells.1 TMZ is rapidly and completely absorbed from the gastrointestinal tract after oral administration and readily crosses the blood-brain barrier.1 Formulations containing TMZ are effective in a variety of types of cancer, including aggressive brain cancers.1,2,3
