Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1,4-dioxadispiro[4.2.5⁸.2⁵]pentadecan-11-one (CAS 2386947-99-3), a certified reference material (molecular formula C13H20O3, MW 224.30 g/mol) for analytical method development and quality control.
The molecular framework of 1,4-dioxadispiro[4.2.5⁸.2⁵]pentadecan-11-one (C13H20O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
