Chemical Structure
Description
The occurrence of 11-AMINO-1-UNDECANETHIOL is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 11-AMINO-1-UNDECANETHIOL (CAS 155638-19-0), a certified reference material (molecular formula C11H25NS, MW 203.39 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, 11-AMINO-1-UNDECANETHIOL is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 203.39 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.
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.
