Chemical Structure

Methylexo-7-oxabicyclo[2.2.1]heptane-2-carboxylate CAS 17791-34-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Methylexo-7-oxabicyclo[2.2.1]heptane-2-carboxylate (CAS 17791-34-3), molecular formula C8H12O3 and molecular weight 156.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methylexo-7-oxabicyclo[2.2.1]heptane-2-carboxylate (C8H12O3) 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).

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.
