Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,4',4'',4'''-(Benzene-1,2,4,5-tetrayltetrakis(ethyne-2,1-diyl))tetrabenzoicacid (CAS 1569900-69-1) is a high-purity analytical reference standard with the molecular formula C42H22O8 and a molecular weight of 654.62 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4,4',4'',4'''-(Benzene-1,2,4,5-tetrayltetrakis(ethyne-2,1-diyl))tetrabenzoicacid is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 654.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 4,4',4'',4'''-(Benzene-1,2,4,5-tetrayltetrakis(ethyne-2,1-diyl))tetrabenzoicacid 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.
