Chemical Structure
Description
D-(+)-Cellopentaose (CAS 2240-27-9), molecular formula C30H52O26 and molecular weight 828.72 g/mol, is a CATO reference standard with documented purity and traceability.
D-(+)-Cellopentaose (C30H52O26) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 D-(+)-Cellopentaose 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.
