Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4,4'-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))diphthalic acid (CAS 38103-05-8), a certified reference material (molecular formula C31H24O10, MW 556.52 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4,4'-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))diphthalic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 556.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 4,4'-((Propane-2,2-diylbis(4,1-phenylene))bis(oxy))diphthalic acid 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.
