About Eltenac

Eltenac (CAS 72895-88-6) is a stable isotope labelled standard offered by Vaqora Chemicals. Its molecular formula is C12H9Cl2NO2S and its molecular weight is 302.2 g/mol. The IUPAC name is 2-[4-(2,6-dichloroanilino)thiophen-3-yl]acetic acid. It is also known as 4-(2,6-dichloroanilino)-3-thiophenacetic acid.

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 “Danger”, 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. Buyers come mainly from 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.
