Chlorophyll B CAS 519-62-0 chemical structure

Description

As a certified reference material (CRM), Chlorophyll B meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies Chlorophyll B (CAS 519-62-0), a certified reference material (molecular formula C55H70MgN4O6, MW 907.47 g/mol) for analytical method development and quality control.

Chlorophyll B (C55H70MgN4O6) 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.
