Chemical Structure

Sunflower trypsin inhibitor 1 CAS 245080-24-4 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

Sunflower trypsin inhibitor 1 (CAS 245080-24-4) is a high-purity analytical reference standard with the molecular formula C67H104N18O18S2 and a molecular weight of 1513.78 g/mol.

Sunflower trypsin inhibitor 1 (C67H104N18O18S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
