Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
Vanadyl 2,9,16,23-tetraphenoxy-29H,31H-phthalocyanine (CAS 109738-21-8), molecular formula C56H32N8O5V and molecular weight 947.85 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, Vanadyl 2,9,16,23-tetraphenoxy-29H,31H-phthalocyanine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 947.85 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
