2-Bromo-N-(1-ethyl-1h-pyrazol-4-yl)-4-fluorobenzamide CAS 1154950-40-9

Description

2-Bromo-N-(1-ethyl-1h-pyrazol-4-yl)-4-fluorobenzamide (CAS 1154950-40-9), molecular formula C12H11BrFN3O and molecular weight 312.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Bromo-N-(1-ethyl-1h-pyrazol-4-yl)-4-fluorobenzamide (C12H11BrFN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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-N-(1-ethyl-1h-pyrazol-4-yl)-4-fluorobenzamide 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.
