Chemical Structure

K19 Dye CAS 847665-45-6 chemical structure

Description

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

K19 Dye (CAS 847665-45-6) is a high-purity analytical reference standard with the molecular formula C52H50N6O6RuS2H and a molecular weight of 1021.21 g/mol.

Structurally, K19 Dye (C52H50N6O6RuS2H) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 30.5, corresponding to approximately 30 ring(s) or double-bond equivalent(s). With a molecular weight of 1021.21 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), K19 Dye 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.
