About Isouridine

Isouridine is an impurity of Uridine carrying the CAS registry number 6745-33-1. With the molecular formula C9H12N2O6, it has a molar mass of 244.2 g/mol. The IUPAC name is 3-[3,4-dihydroxy-5-(hydroxymethyl)oxolan-2-yl]-1H-pyrimidine-2,4-dione. Common synonyms include 3-pentofuranosylpyrimidine-2,4(1h,3h)-dione and d,l-arabinofuranosyluracil.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Good laboratory practice and suitable PPE are recommended during handling.

As a characterised impurity of Uridine, it is used for analytical method development, method validation (AMV) and routine quality-control testing, and it supports ANDA and DMF regulatory filings. Typical end-use sectors are 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.
