Chemical Structure
Description
The occurrence of 5-Azoniaspiro[4.4]nonane Bromide is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Azoniaspiro[4.4]nonane Bromide (CAS 16450-38-7), molecular formula C8H16NBr and molecular weight 206.13 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Azoniaspiro[4.4]nonane Bromide (C8H16NBr) contains bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 206.13 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.
