Chemical Structure
Description
The occurrence of FmocNH-PEG3-CH2CH2NH2 (hydrochloride) is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies FmocNH-PEG3-CH2CH2NH2 (hydrochloride) (CAS 906079-91-2), a certified reference material (molecular formula C23H30N2O5HCl, MW 450.96 g/mol) for analytical method development and quality control.
FmocNH-PEG3-CH2CH2NH2 (hydrochloride) (C23H30N2O5HCl) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
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.
