Description
CATO manufactures Cy5.5 dbco under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Cy5.5 dbco (CAS 1857352-95-4) is a high-purity analytical reference standard with the molecular formula C59H58N4O14S4 and a molecular weight of 1175.37 g/mol.
Structurally, Cy5.5 dbco (C59H58N4O14S4) 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 33.0, corresponding to approximately 33 ring(s) or double-bond equivalent(s). With a molecular weight of 1175.37 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).
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.
