Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Fmoc-2-amino-5-phenyl(2-I)-L-pentanoic acid.
Fmoc-2-amino-5-phenyl(2-I)-L-pentanoic acid (CAS 2349773-68-6) is a high-purity analytical reference standard with the molecular formula C26H24INO4 and a molecular weight of 541.38 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, Fmoc-2-amino-5-phenyl(2-I)-L-pentanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 541.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
