Dichloro[1,3-dihydro-1-(2-methoxyethyl)-3-[(3-methoxyphenyl)methyl]-2H-benzimidazol-2-ylidene](pyridine)palladium (CAS 2304464-54-6), molecular formula C23H26Cl2N3O2Pd and molecular weight 553.80 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Dichloro[1,3-dihydro-1-(2-methoxyethyl)-3-[(3-methoxyphenyl)methyl]-2H-benzimidazol-2-ylidene](pyridine)palladium (C23H26Cl2N3O2Pd) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 553.80 g/mol, it falls into the moderately-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.
