Chemical Structure
Description
The occurrence of 2,8-Dimethyl-1-thia-3,8-diazaspiro[4.5]Decane is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,8-Dimethyl-1-thia-3,8-diazaspiro[4.5]Decane (CAS 1235734-26-5) is a high-purity analytical reference standard with the molecular formula C9H18N2S and a molecular weight of 186.32 g/mol.
Structurally, 2,8-Dimethyl-1-thia-3,8-diazaspiro[4.5]Decane (C9H18N2S) contains a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 186.32 g/mol, it falls into the medium-molecular-weight range. 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.
