About Tolmetin

Vaqora Chemicals supplies Tolmetin, a high-purity reference standard of Tolmetin registered under CAS number 26171-23-3. With the molecular formula C15H15NO3, it has a molar mass of 257.28 g/mol. Systematically, it is named 2-[1-methyl-5-(4-methylbenzoyl)pyrrol-2-yl]acetic acid. Alternative names: 1-Methyl-5-p-toluoylpyrrole-2-acetic acid and Tolmetine.

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.

As a reference sample of Tolmetin, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

We offer Tolmetin in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide. Stock is available for quick dispatch.
