Chemical Structure

4,4'-Oxybis(butan-2-ol) CAS 821-33-0 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 4,4'-Oxybis(butan-2-ol).

4,4'-Oxybis(butan-2-ol) (CAS 821-33-0) is a high-purity analytical reference standard with the molecular formula C8H18O3 and a molecular weight of 162.23 g/mol.

The molecular framework of 4,4'-Oxybis(butan-2-ol) (C8H18O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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'-Oxybis(butan-2-ol) 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.
