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.
Heat Shock Protein (hsp) Fragment trifluoroacetate salt (CAS 165245-21-6), molecular formula C63H113N22O25PSC2HF3O2 and molecular weight 1755.78 g/mol, is a CATO reference standard with documented purity and traceability.
Heat Shock Protein (hsp) Fragment trifluoroacetate salt (C63H113N22O25PSC2HF3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
