Cytosine-d2

Cytosine-d2 is intended for use as an internal standard for the quantification of cytosine 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: 6-amino-2(1H)-pyrimidinone-4,5-d2. CAS Number: 106391-24-6. Molecular Formula: C4H3D2N3O.
