Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 885.18 g/mol gives Pheophytin b distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pheophytin b (CAS 3147-18-0) is a high-purity analytical reference standard with the molecular formula C55H72N4O6 and a molecular weight of 885.18 g/mol.
Pheophytin b (C55H72N4O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Pheophytin b 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.
