Chemical Structure

1,7-Dioxaspiro[4.4]nonan-4-one CAS 2138397-15-4 chemical structure

Description

As a certified reference material (CRM), 1,7-Dioxaspiro[4.4]nonan-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

1,7-Dioxaspiro[4.4]nonan-4-one (CAS 2138397-15-4) is a high-purity analytical reference standard with the molecular formula C7H10O3 and a molecular weight of 142.15 g/mol.

The molecular framework of 1,7-Dioxaspiro[4.4]nonan-4-one (C7H10O3) 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).

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.
