2,7-Dibromo-4,9-dihydro-4,4,9,9-tetraoctyl-s-indaceno[1,2-b:5,6-b′]dithiophene CAS 1209012-33-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 873.02 g/mol gives 2,7-Dibromo-4,9-dihydro-4,4,9,9-tetraoctyl-s-indaceno[1,2-b:5,6-b′]dithiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,7-Dibromo-4,9-dihydro-4,4,9,9-tetraoctyl-s-indaceno[1,2-b:5,6-b′]dithiophene (CAS 1209012-33-8), molecular formula C48H72Br2S2 and molecular weight 873.02 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,7-Dibromo-4,9-dihydro-4,4,9,9-tetraoctyl-s-indaceno[1,2-b:5,6-b′]dithiophene (C48H72Br2S2) is characterized by sulfur-containing functionality, bromine substitution, a polycyclic aromatic 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), 2,7-Dibromo-4,9-dihydro-4,4,9,9-tetraoctyl-s-indaceno[1,2-b:5,6-b′]dithiophene 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.
