Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Atriopeptin III (rat) (CAS 90817-13-3) is a high-purity analytical reference standard with the molecular formula C107H165N35O34S2 and a molecular weight of 2549.83 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Atriopeptin III (rat) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 2549.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Atriopeptin III (rat) 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.
