Chemical Structure

Ethyl 4-bromo-5-fluoro-2,3-dimethyl-1H-indole-7-carboxylate CAS 1912446-33-3 chemical structure

Description

Ethyl 4-bromo-5-fluoro-2,3-dimethyl-1H-indole-7-carboxylate (CAS 1912446-33-3), molecular formula C13H13BrFNO2 and molecular weight 314.15 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethyl 4-bromo-5-fluoro-2,3-dimethyl-1H-indole-7-carboxylate (C13H13BrFNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 314.15 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
