Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 255.11 g/mol gives 1-[(4-bromophenyl)methyl]cyclopropane-1-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-[(4-bromophenyl)methyl]cyclopropane-1-carboxylic acid (CAS 29765-45-5), molecular formula C11H11BrO2 and molecular weight 255.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[(4-bromophenyl)methyl]cyclopropane-1-carboxylic acid (C11H11BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 1-[(4-bromophenyl)methyl]cyclopropane-1-carboxylic acid 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.
