Chemical Structure
Description
Owing to an aromatic ring system, 1,3-Diethylbenzene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.22 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).
1,3-Diethylbenzene (CAS 141-93-5), molecular formula C10H14 and molecular weight 134.22 g/mol, is a CATO reference standard with documented purity and traceability.
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), 1,3-Diethylbenzene 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.
