Chemical Structure

3-(tert-Butyl)cyclopentanone CAS 5581-94-2 chemical structure

Description

The occurrence of 3-(tert-Butyl)cyclopentanone is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(tert-Butyl)cyclopentanone (CAS 5581-94-2) is a high-purity analytical reference standard with the molecular formula C9H16O and a molecular weight of 140.22 g/mol.

The molecular framework of 3-(tert-Butyl)cyclopentanone (C9H16O) is characterized by 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 3-(tert-Butyl)cyclopentanone 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.
