About Triethyl Phosphate-d15

Triethyl Phosphate-d15 is a stable isotope labelled standard carrying the CAS registry number 135942-11-9. The compound has the formula C6H15O4P, corresponding to a molecular weight of 197.25 g/mol. Its systematic (IUPAC) name is tris(1,1,2,2,2-pentadeuterioethyl) phosphate. It is also known as Triethyl-d15 phosphate or Triethyl phosphatel-d15.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

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 Triethyl Phosphate-d15 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
