Chemical Structure

4-methyl-1H-indole-3-carbaldehyde CAS 4771-48-6 chemical structure

Description

CATO supplies 4-methyl-1H-indole-3-carbaldehyde (CAS 4771-48-6), a certified reference material (molecular formula C10H17NO, MW 167.25 g/mol) for analytical method development and quality control.

The molecular framework of 4-methyl-1H-indole-3-carbaldehyde (C10H17NO) is characterized by 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.
