Chemical Structure

7-[tert-Butyl(diphenyl)silyl]oxyheptanal CAS 147974-19-4 chemical structure

Description

The molecular framework of 7-[tert-Butyl(diphenyl)silyl]oxyheptanal (C23H32O2Si) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

7-[tert-Butyl(diphenyl)silyl]oxyheptanal (CAS 147974-19-4), molecular formula C23H32O2Si and molecular weight 368.58 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 7-[tert-Butyl(diphenyl)silyl]oxyheptanal 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.
