Chemical Structure

Ketotifen CAS 34580-13-7 chemical structure

Description

Ketotifen (CAS 34580-13-7) is a high-purity analytical reference standard with the molecular formula C19H19NOS and a molecular weight of 309.43 g/mol.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Ketotifen is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Ketotifen meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
