Chemical Structure

1,4-Diisopropoxybenzene CAS 7495-78-5 chemical structure

Description

1,4-Diisopropoxybenzene (CAS 7495-78-5), molecular formula C12H18O2 and molecular weight 194.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,4-Diisopropoxybenzene (C12H18O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 1,4-Diisopropoxybenzene 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.
