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.
2-[4-[2-Amino-3-[2-Amino-3-[4-(Carboxymethyl)Cyclohexyl]Propyl]Disulfanylpropyl]Cyclohexyl]Acetic Acid; 2,2,2-Trifluoroacetic Acid (CAS 156143-99-6) is a high-purity analytical reference standard with the molecular formula C22H40N2O4S2C2HF3O2 and a molecular weight of 574.71 g/mol.
2-[4-[2-Amino-3-[2-Amino-3-[4-(Carboxymethyl)Cyclohexyl]Propyl]Disulfanylpropyl]Cyclohexyl]Acetic Acid; 2,2,2-Trifluoroacetic Acid (C22H40N2O4S2C2HF3O2) contains a steroid core, an amide group, a sulfone 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.
