Chemical Structure

Ethyl 3-(thiophen-2-yl)piperazine-1-carboxylate CAS 85803-50-5 chemical structure

Description

CATO supplies Ethyl 3-(thiophen-2-yl)piperazine-1-carboxylate (CAS 85803-50-5), a certified reference material (molecular formula C11H16N2O2S, MW 240.32 g/mol) for analytical method development and quality control.

Ethyl 3-(thiophen-2-yl)piperazine-1-carboxylate (C11H16N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Ethyl 3-(thiophen-2-yl)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.
