Chemical Structure

1,9-Dioxaspiro[5.5]undecan-4-one CAS 1330756-23-4 chemical structure

Description

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.

CATO supplies 1,9-Dioxaspiro[5.5]undecan-4-one (CAS 1330756-23-4), a certified reference material (molecular formula C9H14O3, MW 170.21 g/mol) for analytical method development and quality control.

The molecular framework of 1,9-Dioxaspiro[5.5]undecan-4-one (C9H14O3) 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. 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).

CATO manufactures 1,9-Dioxaspiro[5.5]undecan-4-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
