Chemical Structure
Description
The molecular framework of Bis(4-(2-hydroxyethyl)piperazine-1-carboximidamide), sulfuric acid (C7H16N4OH2O4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Bis(4-(2-hydroxyethyl)piperazine-1-carboximidamide), sulfuric acid (CAS 28457-23-0) is a high-purity analytical reference standard with the molecular formula C7H16N4OH2O4S and a molecular weight of 270.30 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.
