Thymine-13C5,15N2

Thymine-13C5,15N2 is intended for use as an internal standard for the quantification of thymine (Cay-38749) 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-13C)-2,4(1H,3H)-pyrimidinedione-2,4,5,6-13C4-1,3-15N2. CAS Number: 2483830-13-1. Synonyms: 5-Methyluracil-13C5,15N2.
