Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 865.04 g/mol gives Cy5.5 acid (tri so3) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Cy5.5 acid (tri so3) (CAS 210834-26-7), a certified reference material (molecular formula C43H48N2O11S3, MW 865.04 g/mol) for analytical method development and quality control.
Based on its molecular formula C43H48N2O11S3, Cy5.5 acid (tri so3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 865.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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), Cy5.5 acid (tri so3) 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.
