Chemical Structure
Description
The occurrence of Microcystin-LW is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Microcystin-LW (CAS 157622-02-1) is a high-purity analytical reference standard with the molecular formula C54H72N8O12 and a molecular weight of 1025.20 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Microcystin-LW is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1025.20 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.
As a certified reference material (CRM), Microcystin-LW 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.
