Description
CATO manufactures ((R)-4-Hydroxy-4-methyl-Orn7)-Phalloidin 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.
((R)-4-Hydroxy-4-methyl-Orn7)-Phalloidin (CAS 87876-22-0) is a high-purity analytical reference standard with the molecular formula C35H49N9O10S and a molecular weight of 787.88 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, ((R)-4-Hydroxy-4-methyl-Orn7)-Phalloidin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 787.88 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.
