Structurally, 20261-85-2 4,22,31,37,38,39,40-Octaoxapentacyclo[32.2.1.17,10.116,19.125,28]tetracontane-3,12,21,30-tetrone, 5,23-diethyl-2,11,14,20,29,32-hexamethyl- A 080555 A 80555 Antibiotic 170t DINACTIN (UPJOHN 170T, LOW MELTING) Dinactin NSC-63925 NSC63925 Nonactin,23-didemethyl-5,23-diethyl- Upjohn 170T (low melting) (C42H68O12) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 764.98 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.
