Description
CATO manufactures Nintedanib E-Isomer 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.
CATO supplies Nintedanib E-Isomer (CAS 1160294-26-7), a certified reference material (molecular formula C31H33N5O4, MW 539.62 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, Nintedanib E-Isomer is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 539.62 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.
