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 N-(4-Bromo-2-fluorophenyl)formamide.
N-(4-Bromo-2-fluorophenyl)formamide (CAS 877134-90-2), molecular formula C7H5BrFNO and molecular weight 218.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(4-Bromo-2-fluorophenyl)formamide (C7H5BrFNO) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), N-(4-Bromo-2-fluorophenyl)formamide 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.
