Description
As a certified reference material (CRM), Sulforhodamine 101 DHPE 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.
CATO supplies Sulforhodamine 101 DHPE (CAS 187099-99-6), a certified reference material (molecular formula C68H102N3O14PS2C6H15N, MW 1381.86 g/mol) for analytical method development and quality control.
Structurally, Sulforhodamine 101 DHPE (C68H102N3O14PS2C6H15N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 18.5, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 1381.86 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
