About 3-Ethynylaniline-D4

3-Ethynylaniline-D4 (CAS 1794883-73-0) is a stable isotope labelled analogue related to Erlotinib offered by Vaqora Chemicals. The compound has the formula C8H3D4N, corresponding to a molecular weight of 121.17 g/mol.

The product is provided as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying 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.

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.
