Chemical Structure

4,5-dimethyl-1H-indole-2-carbaldehyde CAS 58518-55-1 chemical structure

Description

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.

4,5-dimethyl-1H-indole-2-carbaldehyde (CAS 58518-55-1) is a high-purity analytical reference standard with the molecular formula C11H11NO and a molecular weight of 173.21 g/mol.

4,5-dimethyl-1H-indole-2-carbaldehyde (C11H11NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
