Description

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

3-{2-[2-(2-(diphenylamino)-3-{2-[1-(3-sulfonatopropyl)naphtho[1,2-d][1,3]thiazol-1-ium-2-yl]ethenyl}-2-cyclopenten-1-ylidene)ethylidene]naphtho[1,2-d][1,3]thiazol-1- yl}-1-propanesulfonate (CAS 28645-14-9) is a high-purity analytical reference standard with the molecular formula C49H43N3O6S4C6H15N and a molecular weight of 999.33 g/mol.

3-{2-[2-(2-(diphenylamino)-3-{2-[1-(3-sulfonatopropyl)naphtho[1,2-d][1,3]thiazol-1-ium-2-yl]ethenyl}-2-cyclopenten-1-ylidene)ethylidene]naphtho[1,2-d][1,3]thiazol-1- yl}-1-propanesulfonate (C49H43N3O6S4C6H15N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 3-{2-[2-(2-(diphenylamino)-3-{2-[1-(3-sulfonatopropyl)naphtho[1,2-d][1,3]thiazol-1-ium-2-yl]ethenyl}-2-cyclopenten-1-ylidene)ethylidene]naphtho[1,2-d][1,3]thiazol-1- yl}-1-propanesulfonate 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.
