Description
CATO manufactures 1,3-Bis(4-hydroxyphenyl)propane-1,3-dione 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.
1,3-Bis(4-hydroxyphenyl)propane-1,3-dione (CAS 33976-92-0) is a high-purity analytical reference standard with the molecular formula C15H12O4 and a molecular weight of 256.25 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 1,3-Bis(4-hydroxyphenyl)propane-1,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
