Chemical Structure

2-(1-isothiocyanatoethyl)oxolane CAS 1153129-43-1 chemical structure

Description

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.

2-(1-isothiocyanatoethyl)oxolane (CAS 1153129-43-1), molecular formula C7H11NOS and molecular weight 157.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-(1-isothiocyanatoethyl)oxolane is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 157.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
