Chemical Structure

1,2-Di(p-tolyl)ethane CAS 538-39-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 210.31 g/mol gives 1,2-Di(p-tolyl)ethane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,2-Di(p-tolyl)ethane (CAS 538-39-6), a certified reference material (molecular formula C16H18, MW 210.31 g/mol) for analytical method development and quality control.

Owing to a polycyclic aromatic system, 1,2-Di(p-tolyl)ethane is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 210.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 1,2-Di(p-tolyl)ethane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
