Chemical Structure

(porphyrin-5,15-diylbis(4,1-phenylene))diboronicacid CAS 290356-48-8 chemical structure

Description

CATO manufactures (porphyrin-5,15-diylbis(4,1-phenylene))diboronicacid 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.

(porphyrin-5,15-diylbis(4,1-phenylene))diboronicacid (CAS 290356-48-8), molecular formula C32H24B2N4O4 and molecular weight 550.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (porphyrin-5,15-diylbis(4,1-phenylene))diboronicacid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 550.18 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).

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.
