Structurally, (2AS,6aR,6bR,8aR,9R,12bR,14aR)-9-(furan-3-yl)-1,1,8a,12b-tetramethyl-2a,3,6b,7,8,8a,9,12b,14,14a-decahydro-4H,6H,11H-pyrano[4',3':3,3a]isobenzofuro[5,4-f]isochromene-4,11,13(1H)-trione (C26H30O7) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 454.51 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies (2AS,6aR,6bR,8aR,9R,12bR,14aR)-9-(furan-3-yl)-1,1,8a,12b-tetramethyl-2a,3,6b,7,8,8a,9,12b,14,14a-decahydro-4H,6H,11H-pyrano[4',3':3,3a]isobenzofuro[5,4-f]isochromene-4,11,13(1H)-trione (CAS 989-23-1), a certified reference material (molecular formula C26H30O7, MW 454.51 g/mol) for analytical method development and quality control.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
