Chemical Structure
Description
The occurrence of Methyl 6-bromo-1-(sec-butyl)-3-formyl-1H-indole-4-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 6-bromo-1-(sec-butyl)-3-formyl-1H-indole-4-carboxylate (CAS 1346576-38-2), molecular formula C15H16BrNO3 and molecular weight 338.20 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 6-bromo-1-(sec-butyl)-3-formyl-1H-indole-4-carboxylate (C15H16BrNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), Methyl 6-bromo-1-(sec-butyl)-3-formyl-1H-indole-4-carboxylate 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.
