Chemical Structure

(S)-5-Methyl-3-(pentanamidomethyl)hexanoic acid CAS 1786905-72-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(S)-5-Methyl-3-(pentanamidomethyl)hexanoic acid (CAS 1786905-72-3), molecular formula C13H25NO3 and molecular weight 243.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, (S)-5-Methyl-3-(pentanamidomethyl)hexanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.34 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.

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.
