(3s,4s,4ar,5r,9br,10s)-4-(3,5-dihydroxyphenyl)-3,5,10-tris(4-hydr Oxyphenyl)-3,4,4a,5,9b,10-hexahydro-11-oxabenzo[5,6]cyclohepta[1, 2,3,4-jkl]-as-indacene-2,6,8-triol 625096-18-6 (CAS 625096-18-6) is a high-purity analytical reference standard with the molecular formula C42H32O9 and a molecular weight of 680.70 g/mol.

Structurally, (3s,4s,4ar,5r,9br,10s)-4-(3,5-dihydroxyphenyl)-3,5,10-tris(4-hydr Oxyphenyl)-3,4,4a,5,9b,10-hexahydro-11-oxabenzo[5,6]cyclohepta[1, 2,3,4-jkl]-as-indacene-2,6,8-triol 625096-18-6 (C42H32O9) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 27.0, corresponding to approximately 27 ring(s) or double-bond equivalent(s). With a molecular weight of 680.70 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.
