N-{2-[(4-bromophenyl)sulfanyl]ethyl}-4-fluorobenzamide CAS 338955-70-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-{2-[(4-bromophenyl)sulfanyl]ethyl}-4-fluorobenzamide.

N-{2-[(4-bromophenyl)sulfanyl]ethyl}-4-fluorobenzamide (CAS 338955-70-7), molecular formula C15H13BrFNOS and molecular weight 354.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-{2-[(4-bromophenyl)sulfanyl]ethyl}-4-fluorobenzamide (C15H13BrFNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
