Chemical Structure
Description
N2-(((9H-Fluoren-9-yl)methoxy)carbonyl)-N6-(N-methyl-N-((2,2,4,6,7-pentamethyl-2,3-dihydrobenzofuran-5-yl)sulfonyl)carbamimidoyl)-D-lysine (CAS 2044710-73-6) is a high-purity analytical reference standard with the molecular formula C36H44N4O7S and a molecular weight of 676.82 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N2-(((9H-Fluoren-9-yl)methoxy)carbonyl)-N6-(N-methyl-N-((2,2,4,6,7-pentamethyl-2,3-dihydrobenzofuran-5-yl)sulfonyl)carbamimidoyl)-D-lysine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 676.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
