Chemical Structure

Tert-butyl 4-(4-fluoro-2-nitrophenyl)piperazine-1-carboxylate CAS 874814-94-5 chemical structure

Description

The occurrence of Tert-butyl 4-(4-fluoro-2-nitrophenyl)piperazine-1-carboxylate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tert-butyl 4-(4-fluoro-2-nitrophenyl)piperazine-1-carboxylate (CAS 874814-94-5), molecular formula C15H20FN3O4 and molecular weight 325.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Tert-butyl 4-(4-fluoro-2-nitrophenyl)piperazine-1-carboxylate (C15H20FN3O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.

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), Tert-butyl 4-(4-fluoro-2-nitrophenyl)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.
