Chemical Structure

1,4-Dioxaspiro[4,4]nonane, 97% CAS 176-32-9 chemical structure

Description

The molecular framework of 1,4-Dioxaspiro[4,4]nonane, 97% (C7H12O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

1,4-Dioxaspiro[4,4]nonane, 97% (CAS 176-32-9), molecular formula C7H12O2 and molecular weight 128.17 g/mol, is a CATO reference standard with documented purity and traceability.

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.
