Description

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.

3,5-Bis-(4-bromo-benzylidenE)-1-propyl-piperidin-4-one (CAS 412957-50-7), molecular formula C22H21Br2NO and molecular weight 475.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,5-Bis-(4-bromo-benzylidenE)-1-propyl-piperidin-4-one (C22H21Br2NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine 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 475.22 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
