Chemical Structure

[1,1’-Bipyrrole]-2,2’,5,5’-tetraone CAS 6903-84-0 chemical structure

Description

The occurrence of [1,1’-Bipyrrole]-2,2’,5,5’-tetraone is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies [1,1’-Bipyrrole]-2,2’,5,5’-tetraone (CAS 6903-84-0), a certified reference material (molecular formula C8H4N2O4, MW 192.13 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, [1,1’-Bipyrrole]-2,2’,5,5’-tetraone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), [1,1’-Bipyrrole]-2,2’,5,5’-tetraone 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.
