The molecular framework of (S)-7-tert-Butoxycarbonylamino-3-(9H-fluoren-9-ylmethoxycarbonylamino)-heptanoic acid fmoc-l-beta-homolysine(boc) fmoc-l-beta-homolysine (boc) fmoc-beta-homolys(boc)-oh fmoc-l-n-omega-boc-beta-homolysine fmoc-l-beta-homo-lys(boc)-oh fmoc-beta-holys(boc)-oh heptanoic acid, 7-[[(1,1-dimethylethoxy)carbonyl]amino]-3-[[(9h-fluoren-9-ylmethoxy)carbonyl]amino]- n-beta-fmoc-n-omega-boc-l-beta-homolysine fmoc-lys(boc)-(c*ch2)oh 203854-47-1 (C27H46N2O6) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
