About D6 Isoquinoline impurity

D6 Isoquinoline impurity is a stable isotope labelled analogue related to Deutetrabenazine carrying the CAS registry number 1221885-61-5. Its molecular formula is C11H13NO2 and its molecular weight is 197.26 g/mol. The IUPAC name is 6,7-bis(trideuteriomethoxy)-3,4-dihydroisoquinoline. Common synonyms include 3,4-Dihydro-6,7-di(methoxy-d3)isoquinoline and Isoquinoline, 3,4-dihydro-6,7-di(methoxy-d3)-.

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. Good laboratory practice and suitable PPE are recommended during handling.

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 D6 Isoquinoline impurity in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
