Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Chloro-3-methylphenoxy)-5-fluorophenylamine 4107AF 946729-49-3 C13H11ClFNO.
2-(4-Chloro-3-methylphenoxy)-5-fluorophenylamine 4107AF 946729-49-3 C13H11ClFNO (CAS 946729-49-3) is a high-purity analytical reference standard with the molecular formula C13H11ClFNO and a molecular weight of 251.68 g/mol.
The molecular framework of 2-(4-Chloro-3-methylphenoxy)-5-fluorophenylamine 4107AF 946729-49-3 C13H11ClFNO (C13H11ClFNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-(4-Chloro-3-methylphenoxy)-5-fluorophenylamine 4107AF 946729-49-3 C13H11ClFNO 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.
