Chemical Structure

1-[5-[1-(tert-Butoxy)ethyl]-1-(3-fluoro-4-methylbenzyl)-2-piperazinyl]-1-ethanol CAS 1353505-79-9 chemical structure

Description

1-[5-[1-(tert-Butoxy)ethyl]-1-(3-fluoro-4-methylbenzyl)-2-piperazinyl]-1-ethanol (CAS 1353505-79-9) is a high-purity analytical reference standard with the molecular formula C20H33FN2O2 and a molecular weight of 352.49 g/mol.

Based on its molecular formula C20H33FN2O2, 1-[5-[1-(tert-Butoxy)ethyl]-1-(3-fluoro-4-methylbenzyl)-2-piperazinyl]-1-ethanol contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 352.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-[5-[1-(tert-Butoxy)ethyl]-1-(3-fluoro-4-methylbenzyl)-2-piperazinyl]-1-ethanol 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.
