About Norfloxacin-d5

Norfloxacin-d5 is a stable isotope labelled analogue related to Norfloxacin carrying the CAS registry number 1015856-57-1. With the molecular formula C16H18FN3O3, it has a molar mass of 324.36 g/mol. Systematically, it is named 6-fluoro-4-oxo-1-(1,1,2,2,2-pentadeuterioethyl)-7-piperazin-1-ylquinoline-3-carboxylic acid. It is also known as Norfloxacin-D5 (ethyl-D5) or TMIH-0398.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

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. It is used across pharmaceutical manufacturing and academic and industrial research.

We offer Norfloxacin-d5 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
