(E)-({6-[(4-chlorophenyl)sulfanyl]pyridin-3-yl}methylidene)[(4-fluorophenyl)methoxy]amine 338967-03-6 6L-329S (CAS 338967-03-6), molecular formula C19H14ClFN2OS and molecular weight 372.84 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-({6-[(4-chlorophenyl)sulfanyl]pyridin-3-yl}methylidene)[(4-fluorophenyl)methoxy]amine 338967-03-6 6L-329S (C19H14ClFN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/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 372.84 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.
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.
