Chemical Structure
Description
The occurrence of 1,2,4,5-Tetraisopropylbenzene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,2,4,5-Tetraisopropylbenzene (CAS 27322-46-9), a certified reference material (molecular formula C18H30, MW 246.43 g/mol) for analytical method development and quality control.
Owing to an aromatic ring system, 1,2,4,5-Tetraisopropylbenzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 246.43 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), 1,2,4,5-Tetraisopropylbenzene 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.
