Chemical Structure
Description
CATO supplies 1-Ethyl-2,7-dimethyl-1H-indole-3-carbaldehyde (CAS 893729-66-3), a certified reference material (molecular formula C13H15NO, MW 201.26 g/mol) for analytical method development and quality control.
1-Ethyl-2,7-dimethyl-1H-indole-3-carbaldehyde (C13H15NO) 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.
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.
