Chemical Structure

4,4′-DDOH CAS 2642-82-2 chemical structure

Description

Owing to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 4,4′-DDOH is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 267.15 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).

4,4′-DDOH (CAS 2642-82-2), molecular formula C14H12Cl2O and molecular weight 267.15 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 4,4′-DDOH 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.
