Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 219.24 g/mol gives 5-Methoxy-1,3-dimethyl-1H-indole-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Methoxy-1,3-dimethyl-1H-indole-2-carboxylic acid (CAS 59908-57-5), a certified reference material (molecular formula C12H13NO3, MW 219.24 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methoxy-1,3-dimethyl-1H-indole-2-carboxylic acid (C12H13NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
