Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Proinsulin C-Peptide (55-89) (human).
CATO supplies Proinsulin C-Peptide (55-89) (human) (CAS 11097-48-6), a certified reference material (molecular formula C153H259N49O52, MW 3617.00 g/mol) for analytical method development and quality control.
Proinsulin C-Peptide (55-89) (human) (C153H259N49O52) 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.
As a certified reference material (CRM), Proinsulin C-Peptide (55-89) (human) 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.
