About Oxolinic Acid-d5

Listed under CAS 1189890-98-9, Oxolinic Acid-d5 is a stable isotope labelled analogue related to Oxolinic acid available from Vaqora Chemicals. The compound has the formula C13H11NO5, corresponding to a molecular weight of 266.26 g/mol. Its systematic (IUPAC) name is 8-oxo-5-(1,1,2,2,2-pentadeuterioethyl)-[1,3]dioxolo[4,5-g]quinoline-7-carboxylic acid. Common synonyms include Oxolinic-d5 Acid (ethyl-d5).

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 “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

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.
