(S)-4-(4-Bromo-2-nitrophenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786811-31-1 CAS 1786811-31-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-4-(4-Bromo-2-nitrophenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786811-31-1.

CATO supplies (S)-4-(4-Bromo-2-nitrophenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786811-31-1 (CAS 1786811-31-1), a certified reference material (molecular formula C16H20BrN3O6, MW 430.25 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, (S)-4-(4-Bromo-2-nitrophenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786811-31-1 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 430.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (S)-4-(4-Bromo-2-nitrophenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786811-31-1 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.
