Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(5,6-Dichloro-1-(2,6-dichlorobenzyl)-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one.
3-(5,6-Dichloro-1-(2,6-dichlorobenzyl)-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one (CAS 338774-41-7) is a high-purity analytical reference standard with the molecular formula C19H11Cl4N3O and a molecular weight of 439.12 g/mol.
Structurally, 3-(5,6-Dichloro-1-(2,6-dichlorobenzyl)-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one (C19H11Cl4N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 439.12 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
