About Cytidine D2

Vaqora Chemicals supplies Cytidine D2, a stable isotope labelled analogue related to Cytidine monophosphate registered under CAS number 40632-25-5. Formula C9H13N3O5, molecular weight 245.23 g/mol. The IUPAC name is 5,6-dideuterio-1-[(2R,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)oxolan-2-yl]-4-iminopyrimidin-2-one. Common synonyms include Cytidine-5,6-d2 and TMID-0808.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Handle it with standard laboratory precautions and appropriate personal protective equipment.

Its mass shift relative to the unlabelled analyte makes it a dependable internal standard for LC-MS/MS assays, improving accuracy in bioanalysis, therapeutic drug monitoring and method validation. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
