Chemical Structure
Description
[1-(4-Amino-benzenesulfonyl)-piperidin-4-yl]-carbamic acid tert-butyl ester hydrochloride (CAS 1228070-81-2) is a high-purity analytical reference standard with the molecular formula C16H25N3O4SHCl and a molecular weight of 391.91 g/mol.
[1-(4-Amino-benzenesulfonyl)-piperidin-4-yl]-carbamic acid tert-butyl ester hydrochloride (C16H25N3O4SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), [1-(4-Amino-benzenesulfonyl)-piperidin-4-yl]-carbamic acid tert-butyl ester hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
