Description
As a certified reference material (CRM), 1-Acetyl-5-fluoro-1H-indole-3-carboxylic acid 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.
1-Acetyl-5-fluoro-1H-indole-3-carboxylic acid (CAS 1260799-33-4), molecular formula C11H8FNO3 and molecular weight 221.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Acetyl-5-fluoro-1H-indole-3-carboxylic acid (C11H8FNO3) 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 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.
