2-Bromo-1-(5-iodothiophen-2-yl)ethan-1-one CAS 34800-30-1

Description

The occurrence of 2-Bromo-1-(5-iodothiophen-2-yl)ethan-1-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Bromo-1-(5-iodothiophen-2-yl)ethan-1-one (CAS 34800-30-1), molecular formula C6H4BrIOS and molecular weight 330.97 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Bromo-1-(5-iodothiophen-2-yl)ethan-1-one (C6H4BrIOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-Bromo-1-(5-iodothiophen-2-yl)ethan-1-one 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.
