Chemical Structure
Description
The occurrence of (E)-[(2,4-Dichlorophenyl)methoxy]({2-[(2,4-dichlorophenyl)sulfanyl]pyridin-3-yl}methylidene)amine is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-[(2,4-Dichlorophenyl)methoxy]({2-[(2,4-dichlorophenyl)sulfanyl]pyridin-3-yl}methylidene)amine (CAS 478031-13-9), molecular formula C19H12Cl4N2OS and molecular weight 458.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-[(2,4-Dichlorophenyl)methoxy]({2-[(2,4-dichlorophenyl)sulfanyl]pyridin-3-yl}methylidene)amine (C19H12Cl4N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 458.19 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
