Chemical Structure

trans-7,8,9,10-tetrahydro-benzo[a]pyrene-9,10-diol CAS 61441-24-5 chemical structure

Description

trans-7,8,9,10-tetrahydro-benzo[a]pyrene-9,10-diol (CAS 61441-24-5) is a high-purity analytical reference standard with the molecular formula C20H16O2 and a molecular weight of 288.34 g/mol.

The molecular framework of trans-7,8,9,10-tetrahydro-benzo[a]pyrene-9,10-diol (C20H16O2) 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).

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 trans-7,8,9,10-tetrahydro-benzo[a]pyrene-9,10-diol 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.
