Chemical Structure
Description
28-Homo Brassinolide (CAS 82373-95-3), molecular formula C29H50O6 and molecular weight 494.70 g/mol, is a CATO reference standard with documented purity and traceability.
28-Homo Brassinolide (C29H50O6) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 28-Homo Brassinolide 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.
