Chemical Structure
Description
The occurrence of 1,4-Dioxaspiro[4.4]nonane-7-carbaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,4-Dioxaspiro[4.4]nonane-7-carbaldehyde (CAS 90199-54-5), a certified reference material (molecular formula C8H12O3, MW 156.18 g/mol) for analytical method development and quality control.
Structurally, 1,4-Dioxaspiro[4.4]nonane-7-carbaldehyde (C8H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 156.18 g/mol, it falls into the medium-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
