Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 656.68 g/mol gives Leurubicin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Leurubicin (CAS 70774-25-3), a certified reference material (molecular formula C33H40N2O12, MW 656.68 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Leurubicin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 656.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Leurubicin 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.
