Description
CATO supplies 2-Oxepanone, polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, bis[hydrogen (2Z)-2-butenedioate] (CAS 71662-45-8), a certified reference material (molecular formula C14H18O9C6H10O2, MW 444.43 g/mol) for analytical method development and quality control.
The molecular framework of 2-Oxepanone, polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, bis[hydrogen (2Z)-2-butenedioate] (C14H18O9C6H10O2) is characterized by a flavonoid core, 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).
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.
