Chemical Structure
Description
The occurrence of 2-Bromo-3-(4-chloro-2-methylphenyl)-1-propene is closely related to chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-3-(4-chloro-2-methylphenyl)-1-propene (CAS 951894-03-4), molecular formula C10H10BrCl and molecular weight 245.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-3-(4-chloro-2-methylphenyl)-1-propene (C10H10BrCl) is characterized by chlorine/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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Bromo-3-(4-chloro-2-methylphenyl)-1-propene 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.
