Chemical Structure

1,2-Bis(m-tolyloxy)ethane CAS 54914-85-1 chemical structure

Description

CATO supplies 1,2-Bis(m-tolyloxy)ethane (CAS 54914-85-1), a certified reference material (molecular formula C16H18O2, MW 242.31 g/mol) for analytical method development and quality control.

Structurally, 1,2-Bis(m-tolyloxy)ethane (C16H18O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 242.31 g/mol, it falls into the medium-molecular-weight range. 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.
