4-tert-Butyl-o-xylene CAS 7397-06-0 chemical structure

Description

4-tert-Butyl-o-xylene (CAS 7397-06-0) is a high-purity analytical reference standard with the molecular formula C12H18 and a molecular weight of 162.27 g/mol.

The molecular framework of 4-tert-Butyl-o-xylene (C12H18) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-tert-Butyl-o-xylene 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.
