12-(1,3,8,10-Tetraoxo-9-(tridecan-7-yl)-9,10-dihydroanthra[2,1,9-def:6,5,10-d'e'f']diisoquinolin-2(1H,3H,8H)-yl)dodecanoic acid CAS 626231-72-9

Description

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.

12-(1,3,8,10-Tetraoxo-9-(tridecan-7-yl)-9,10-dihydroanthra[2,1,9-def:6,5,10-d'e'f']diisoquinolin-2(1H,3H,8H)-yl)dodecanoic acid (CAS 626231-72-9) is a high-purity analytical reference standard with the molecular formula C49H58N2O6 and a molecular weight of 770.99 g/mol.

Structurally, 12-(1,3,8,10-Tetraoxo-9-(tridecan-7-yl)-9,10-dihydroanthra[2,1,9-def:6,5,10-d'e'f']diisoquinolin-2(1H,3H,8H)-yl)dodecanoic acid (C49H58N2O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 770.99 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
