Chemical Structure

(3R,4S,5S)-3-ethoxy-5-methyl-4-(methylamino)heptanoic acid CAS CATO-C3D-262586 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.

CATO supplies (3R,4S,5S)-3-ethoxy-5-methyl-4-(methylamino)heptanoic acid (CAS CATO-C3D-262586), a certified reference material (molecular formula C11H23NO3, MW 217.31 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (3R,4S,5S)-3-ethoxy-5-methyl-4-(methylamino)heptanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
