Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethyl-4-isopropylbenzene.
CATO supplies 1-Ethyl-4-isopropylbenzene (CAS 4218-48-8), a certified reference material (molecular formula C11H16, MW 148.24 g/mol) for analytical method development and quality control.
Owing to an aromatic ring system, 1-Ethyl-4-isopropylbenzene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.24 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.
CATO manufactures 1-Ethyl-4-isopropylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
