Chemical Structure
Description
The molecular framework of tert-Butyl 4-(2-(chlorosulfonyl)ethyl)piperazine-1-carboxylate (C11H21ClN2O4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
tert-Butyl 4-(2-(chlorosulfonyl)ethyl)piperazine-1-carboxylate (CAS 1196146-34-5) is a high-purity analytical reference standard with the molecular formula C11H21ClN2O4S and a molecular weight of 312.81 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), tert-Butyl 4-(2-(chlorosulfonyl)ethyl)piperazine-1-carboxylate 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.
