Chemical Structure
Description
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.
1-(5-Bromo-4-cyclopropylthiophen-2-yl)ethan-1-one (CAS 2302672-24-6), molecular formula C9H9BrOS and molecular weight 245.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(5-Bromo-4-cyclopropylthiophen-2-yl)ethan-1-one (C9H9BrOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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. 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).
As a certified reference material (CRM), 1-(5-Bromo-4-cyclopropylthiophen-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.
