Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 129.22 g/mol gives 5-(methylsulfanyl)pentanenitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-(methylsulfanyl)pentanenitrile (CAS 59121-25-4), a certified reference material (molecular formula C6H11NS, MW 129.22 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, 5-(methylsulfanyl)pentanenitrile is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 129.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
