Description
CATO supplies PACAP (1-38), human, ovine, rat (CAS 137061-48-4), a certified reference material (molecular formula C203H331N63O53S, MW 4534.33 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, PACAP (1-38), human, ovine, rat is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 4534.33 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), PACAP (1-38), human, ovine, 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.
