9-Thia-2-azaspiro[5.5]undecane CAS 86697-02-1

Description

The occurrence of 9-Thia-2-azaspiro[5.5]undecane is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

9-Thia-2-azaspiro[5.5]undecane (CAS 86697-02-1), molecular formula C9H17NS and molecular weight 171.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, sulfur-containing functionality, 9-Thia-2-azaspiro[5.5]undecane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.30 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.

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.
