Chemical Structure
Description
The occurrence of 4-Amino-2,6-difluorophenol is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Amino-2,6-difluorophenol (CAS 126058-97-7), a certified reference material (molecular formula C6H5F2NO, MW 145.11 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H5F2NO, 4-Amino-2,6-difluorophenol contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 145.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-Amino-2,6-difluorophenol 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.
