Acetazolamide-d3

About Acetazolamide-d3

Acetazolamide-d3 is a stable isotope labelled standard carrying the CAS registry number 1189904-01-5. Formula C4H6N4O3S2, molecular weight 225.3 g/mol. Its systematic (IUPAC) name is 2,2,2-trideuterio-N-(5-sulfamoyl-1,3,4-thiadiazol-2-yl)acetamide. Common synonyms include Acetazolamide D3 (methyl D3).

The product is provided as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Handle it with standard laboratory precautions and appropriate personal protective equipment.

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. Our customers for this product work in 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.
