Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
tert-Butyl (R)-2-(2-bromophenyl)piperazine-1-carboxylate (CAS 1260611-38-8), molecular formula C15H21BrN2O2 and molecular weight 341.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl (R)-2-(2-bromophenyl)piperazine-1-carboxylate (C15H21BrN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
CATO manufactures tert-Butyl (R)-2-(2-bromophenyl)piperazine-1-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
