2-Ethynyl-4-fluoroaniline CAS 887903-03-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2-Ethynyl-4-fluoroaniline (CAS 887903-03-9), molecular formula C8H6FN and molecular weight 135.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Ethynyl-4-fluoroaniline (C8H6FN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 2-Ethynyl-4-fluoroaniline 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.
