Chemical Structure
Description
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.
CATO supplies 3-Cyano-6-(2,4-dichlorophenyl)pyridin-2-yl 2,6-dichlorobenzoate (CAS 400075-78-7), a certified reference material (molecular formula C19H8Cl4N2O2, MW 438.09 g/mol) for analytical method development and quality control.
Structurally, 3-Cyano-6-(2,4-dichlorophenyl)pyridin-2-yl 2,6-dichlorobenzoate (C19H8Cl4N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 438.09 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
