About Hydroquinone-d6

Vaqora Chemicals supplies Hydroquinone-d6, a stable isotope labelled analogue related to Hydroquinone registered under CAS number 71589-26-9. With the molecular formula C6H6O2, it has a molar mass of 116.15 g/mol. Its systematic (IUPAC) name is 1,2,4,5-tetradeuterio-3,6-dideuteriooxybenzene. Common synonyms include 1,4-Benzene-2,3,5,6-d4-diol-d2 and (~2~H_4_)Benzene-1,4-(~2~H_2_)diol.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. 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. Our customers for this product work in pharmaceutical manufacturing and academic and industrial research.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, Hydroquinone-d6 is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
