Chemical Structure
Description
The molecular framework of tert-Butyl 4-[(4-fluorobenzene)sulfonyl]piperazine-1-carboxylate (C15H21FN2O4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies tert-Butyl 4-[(4-fluorobenzene)sulfonyl]piperazine-1-carboxylate (CAS 194853-66-2), a certified reference material (molecular formula C15H21FN2O4S, MW 344.40 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
