About Naphthalene-d8

Vaqora Chemicals supplies Naphthalene-d8, a stable isotope labelled analogue related to Naphthalene registered under CAS number 1146-65-2. Its molecular formula is C10H8 and its molecular weight is 136.22 g/mol. The IUPAC name is 1,2,3,4,5,6,7,8-octadeuterionaphthalene. It is also known as (2H8)Naphthalene or Perdeuterated naphthalene.

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. Under GHS it is labelled “Danger”, so handle it with suitable PPE and consult the SDS.

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 Naphthalene-d8 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
