Desacetyl Diltiazem-d4

About Desacetyl Diltiazem-d4

Desacetyl Diltiazem-d4 is a stable isotope labelled analogue related to Diltiazem carrying the CAS registry number 112259-40-2. Formula C20H24N2O3S, molecular weight 376.5 g/mol. It is also known as Deacetyldiltiazem-d4.

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. It is used across 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.
