Polidocanol Impurity 2 (CAS CATO-C4X-29442) is a certified pharmaceutical impurity reference standard with the molecular formula C31H62O12 and a molecular weight of 626.82 g/mol.
Structurally, Polidocanol Impurity 2 (C31H62O12) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 626.82 g/mol, it falls into the high-molecular-weight range.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
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.
