About Iohexol EP Impurity K

Iohexol EP Impurity K (CAS 35453-19-1) is a pharmacopeial impurity of Iohexol offered by Vaqora Chemicals. With the molecular formula C8H4I3NO4, it has a molar mass of 558.83 g/mol. The IUPAC name is 5-amino-2,4,6-triiodobenzene-1,3-dicarboxylic acid. Alternative names: Iohexol - Impurity K and 5-Amino-2,4,6-triiodoisophthalic acid.

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. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

As a characterised impurity of Iohexol, 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.
