Chemical Structure

2-Amino-5-ethoxy-4-fluorobenzenethiol CAS 1343865-59-7 chemical structure

Description

CATO supplies 2-Amino-5-ethoxy-4-fluorobenzenethiol (CAS 1343865-59-7), a certified reference material (molecular formula C8H10FNOS, MW 187.23 g/mol) for analytical method development and quality control.

The molecular framework of 2-Amino-5-ethoxy-4-fluorobenzenethiol (C8H10FNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), 2-Amino-5-ethoxy-4-fluorobenzenethiol 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.
