Chemical Structure
Description
The occurrence of 5-FLUORO-1H-INDOLE-2-CARBOXYLIC ACID METHYL ESTER is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-FLUORO-1H-INDOLE-2-CARBOXYLIC ACID METHYL ESTER (CAS 167631-84-7), molecular formula C10H8FNO2 and molecular weight 193.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H8FNO2, 5-FLUORO-1H-INDOLE-2-CARBOXYLIC ACID METHYL ESTER contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 193.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
