Chemical Structure
Description
N-(2-chlorophenyl)-2-((4-(4-chlorophenyl)-3-cyano-6-phenylpyridin-2-yl)thio)acetamide (CAS 332385-53-2), molecular formula C26H17Cl2N3OS and molecular weight 490.40 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(2-chlorophenyl)-2-((4-(4-chlorophenyl)-3-cyano-6-phenylpyridin-2-yl)thio)acetamide (C26H17Cl2N3OS) 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 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 490.40 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.
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.
