    Product Description

    Thymine-13C5,15N2 is intended for use as an internal standard for the quantification of thymine (Item No. 38749) by GC- or LC-MS. Thymine is a pyrimidine base.1 It forms complementary base pairs with the purine adenine (Item No. 18148) in DNA.1 Thymine is produced by the catabolism of thymidine (Item No. 20519) via thymidine phosphorylase.2 It is replaced with uracil (Item No. 26088) in RNA.3

    WARNING This product is not for human or veterinary use.
