Chemical Structure
Description
CATO supplies (S)-tert-Butyl 3-(3-amino-5-(3-fluorophenyl)thiophene-2-carboxamido)piperidine-1-carboxylate (CAS 1192875-04-9), a certified reference material (molecular formula C21H26FN3O3S, MW 419.51 g/mol) for analytical method development and quality control.
Structurally, (S)-tert-Butyl 3-(3-amino-5-(3-fluorophenyl)thiophene-2-carboxamido)piperidine-1-carboxylate (C21H26FN3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 419.51 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.
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.
