4-Chloro-2-((4-chlorophenyl)thio)-1-phenyl-1h-imidazole-5-carbaldehyde (CAS 1235440-06-8), molecular formula C16H10Cl2N2OS and molecular weight 349.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Chloro-2-((4-chlorophenyl)thio)-1-phenyl-1h-imidazole-5-carbaldehyde (C16H10Cl2N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 349.23 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.
