Thymine-d4

Thymine-d4 is intended for use as an internal standard for the quantification of thymine by GC- or LC-MS. Thymine is a pyrimidine base. It forms complementary base pairs with the purine adenine (Cay-18148) in DNA. Thymine is produced by the catabolism of thymidine (Cay-20519) via thymidine phosphorylase. It is replaced with uracil (Cay-26088) in RNA.Formal Name: 5-(methyl-d3)pyrimidine-2,4(1H,3H)-dione-6-d. CAS Number: 156054-85-2. Molecular Formula: C5H2D4N2O2. Formula Weight: 130.1.
