Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-3,3-dimethyl-3-fluorobutyrophenone.
4-Bromo-3,3-dimethyl-3-fluorobutyrophenone (CAS 898764-62-0), molecular formula C12H14BrFO and molecular weight 273.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-3,3-dimethyl-3-fluorobutyrophenone (C12H14BrFO) is characterized by a hydroxyl group, an ether linkage, fluorine/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), 4-Bromo-3,3-dimethyl-3-fluorobutyrophenone 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.
