Description

Octaethyl 2,2',2'',2''',2'''',2''''',2'''''',2'''''''-((15,35,55,75,95,115,135,155-octa-tert-butyl-1,3,5,7,9,11,13,15(1,3)-octabenzenacyclohexadecaphane-12,32,52,72,92,112,132,152-octayl)octakis(oxy))octaacetate (CAS 92003-63-9) is a high-purity analytical reference standard with the molecular formula C120H160O24 and a molecular weight of 1986.54 g/mol.

Structurally, Octaethyl 2,2',2'',2''',2'''',2''''',2'''''',2'''''''-((15,35,55,75,95,115,135,155-octa-tert-butyl-1,3,5,7,9,11,13,15(1,3)-octabenzenacyclohexadecaphane-12,32,52,72,92,112,132,152-octayl)octakis(oxy))octaacetate (C120H160O24) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 41.0, corresponding to approximately 41 ring(s) or double-bond equivalent(s). With a molecular weight of 1986.54 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.

As a certified reference material (CRM), Octaethyl 2,2',2'',2''',2'''',2''''',2'''''',2'''''''-((15,35,55,75,95,115,135,155-octa-tert-butyl-1,3,5,7,9,11,13,15(1,3)-octabenzenacyclohexadecaphane-12,32,52,72,92,112,132,152-octayl)octakis(oxy))octaacetate 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.
