1,3-Dibromo-5-dodecyl-4H-thieno[3,4-c]pyrrole-4,6(5H)-dione CAS 773881-47-3

Description

As a certified reference material (CRM), 1,3-Dibromo-5-dodecyl-4H-thieno[3,4-c]pyrrole-4,6(5H)-dione 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.

1,3-Dibromo-5-dodecyl-4H-thieno[3,4-c]pyrrole-4,6(5H)-dione (CAS 773881-47-3) is a high-purity analytical reference standard with the molecular formula C18H25Br2NO2S and a molecular weight of 479.27 g/mol.

Based on its molecular formula C18H25Br2NO2S, 1,3-Dibromo-5-dodecyl-4H-thieno[3,4-c]pyrrole-4,6(5H)-dione contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 479.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
