Chemical Structure

4-fluoro-5-nitro-1H-indole CAS 1003858-69-2 chemical structure

Description

The occurrence of 4-fluoro-5-nitro-1H-indole is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-fluoro-5-nitro-1H-indole (CAS 1003858-69-2) is a high-purity analytical reference standard with the molecular formula C8H13FN2O2 and a molecular weight of 188.20 g/mol.

Structurally, 4-fluoro-5-nitro-1H-indole (C8H13FN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 188.20 g/mol, it falls into the medium-molecular-weight range. 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.
