Cytosine-13C,15N2

Cytosine-13C,15N2 is intended for use as an internal standard for the quantification of cytosine (Cay-36219) by GC- or LC-MS. Cytosine is a pyrimidine base. It forms complementary base pairs with the purine guanine (Cay-34248) in DNA and RNA and is a precursor of uracil (Cay-26088). Methylation of cytosine is a key epigenetic mark that plays a role in gene regulation.Formal Name: 4-amino-2(1H)-pyrimidinone-2-13C-1,3-15N2. CAS Number: 181517-10-2.
