2,5,7,10-Tetraoxaundecane (CAS 4431-83-8), molecular formula C7H16O4 and molecular weight 164.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,5,7,10-Tetraoxaundecane (C7H16O4) 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.
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.
