Description
CATO manufactures 1-(5-Fluoro-2-(methylamino)phenyl)ethanone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
1-(5-Fluoro-2-(methylamino)phenyl)ethanone (CAS 124958-74-3), molecular formula C9H10FNO and molecular weight 167.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(5-Fluoro-2-(methylamino)phenyl)ethanone (C9H10FNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
