Chemical Structure

(Isopropylthio)acetonitrile CAS 23178-01-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 115.20 g/mol gives (Isopropylthio)acetonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(Isopropylthio)acetonitrile (CAS 23178-01-0), molecular formula C5H9NS and molecular weight 115.20 g/mol, is a CATO reference standard with documented purity and traceability.

(Isopropylthio)acetonitrile (C5H9NS) contains a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
