N-tert-Butyloxycarbonyl-D-erythro-sphingosine-2,3-N,O-acetonide-1-phosphate Bis[1-(2-nitrophenyl)ethyl]ester (CAS 207516-26-5), molecular formula C42H64N3O11P and molecular weight 817.94 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-tert-Butyloxycarbonyl-D-erythro-sphingosine-2,3-N,O-acetonide-1-phosphate Bis[1-(2-nitrophenyl)ethyl]ester (C42H64N3O11P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 817.94 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), N-tert-Butyloxycarbonyl-D-erythro-sphingosine-2,3-N,O-acetonide-1-phosphate Bis[1-(2-nitrophenyl)ethyl]ester 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.
