1-Ethyl-4-piperidin-4-yl-piperazine 1-ethyl-4-(piperidin-4-yl)piperazine 1-ethyl-4-piperidin-4-ylpiperazine 202991-77-3 CAS 202991-77-3 chemical structure

Description

The occurrence of 1-Ethyl-4-piperidin-4-yl-piperazine 1-ethyl-4-(piperidin-4-yl)piperazine 1-ethyl-4-piperidin-4-ylpiperazine 202991-77-3 is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Ethyl-4-piperidin-4-yl-piperazine 1-ethyl-4-(piperidin-4-yl)piperazine 1-ethyl-4-piperidin-4-ylpiperazine 202991-77-3 (CAS 202991-77-3), a certified reference material (molecular formula C11H23N3HCl, MW 233.78 g/mol) for analytical method development and quality control.

1-Ethyl-4-piperidin-4-yl-piperazine 1-ethyl-4-(piperidin-4-yl)piperazine 1-ethyl-4-piperidin-4-ylpiperazine 202991-77-3 (C11H23N3HCl) contains chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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-Ethyl-4-piperidin-4-yl-piperazine 1-ethyl-4-(piperidin-4-yl)piperazine 1-ethyl-4-piperidin-4-ylpiperazine 202991-77-3 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.
