Chemical Structure
Description
Cyanine 3 Bihexanoic Acid Dye, Succinimidyl Ester, Potassium Salt (C43H50N4O14S2K) 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).
Cyanine 3 Bihexanoic Acid Dye, Succinimidyl Ester, Potassium Salt (CAS 1311966-47-8), molecular formula C43H50N4O14S2K and molecular weight 950.11 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Cyanine 3 Bihexanoic Acid Dye, Succinimidyl Ester, Potassium Salt 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.
