2,6-Dibromospiro[cyclopenta[2,1-b:3,4-b']dithiophene-4,2'-[1,3]dioxolane] CAS 771579-00-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 394.10 g/mol gives 2,6-Dibromospiro[cyclopenta[2,1-b:3,4-b']dithiophene-4,2'-[1,3]dioxolane] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,6-Dibromospiro[cyclopenta[2,1-b:3,4-b']dithiophene-4,2'-[1,3]dioxolane] (CAS 771579-00-1) is a high-purity analytical reference standard with the molecular formula C11H6Br2O2S2 and a molecular weight of 394.10 g/mol.

The molecular framework of 2,6-Dibromospiro[cyclopenta[2,1-b:3,4-b']dithiophene-4,2'-[1,3]dioxolane] (C11H6Br2O2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 2,6-Dibromospiro[cyclopenta[2,1-b:3,4-b']dithiophene-4,2'-[1,3]dioxolane] 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.
