Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
90433-27-5 1-Bromo-3-(3-methylbut-3-en-1-yl)benzene DTXSID90535472 (CAS 90433-27-5), molecular formula C11H13Br and molecular weight 225.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 90433-27-5 1-Bromo-3-(3-methylbut-3-en-1-yl)benzene DTXSID90535472 (C11H13Br) is characterized by 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).
As a certified reference material (CRM), 90433-27-5 1-Bromo-3-(3-methylbut-3-en-1-yl)benzene DTXSID90535472 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.
