4,4',4'',4'''-(Pyrene-1,3,6,8-tetrayltetrakis(ethyne-2,1-diyl))tetrabenzaldehyde CAS 2438216-59-0 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',4'',4'''-(Pyrene-1,3,6,8-tetrayltetrakis(ethyne-2,1-diyl))tetrabenzaldehyde.

4,4',4'',4'''-(Pyrene-1,3,6,8-tetrayltetrakis(ethyne-2,1-diyl))tetrabenzaldehyde (CAS 2438216-59-0), molecular formula C52H26O4 and molecular weight 714.76 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4',4'',4'''-(Pyrene-1,3,6,8-tetrayltetrakis(ethyne-2,1-diyl))tetrabenzaldehyde (C52H26O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 4,4',4'',4'''-(Pyrene-1,3,6,8-tetrayltetrakis(ethyne-2,1-diyl))tetrabenzaldehyde 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.
