Raloxifene-d4

About Raloxifene-d4

Raloxifene-d4 is a stable isotope labelled analogue related to Raloxifene carrying the CAS registry number 1185076-44-1. Formula C28H27NO4S, molecular weight 477.6 g/mol.

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. 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. 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. SDS and detailed specification sheets can be requested with your quotation.
