About Chlorthalidone-d4

Vaqora Chemicals supplies Chlorthalidone-d4, a stable isotope labelled analogue related to Chlortalidone registered under CAS number 1794941-44-8. With the molecular formula C14H11ClN2O4S, it has a molar mass of 342.8 g/mol. Its systematic (IUPAC) name is 2-chloro-5-(4,5,6,7-tetradeuterio-1-hydroxy-3-oxo-2H-isoindol-1-yl)benzenesulfonamide. Alternative names: TMID-0228.

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.

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.

Vaqora Chemicals supplies Chlorthalidone-d4 in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
