Chemical Structure

Fmoc-Lys(2-chloro-Z)-OH CAS 133970-31-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies Fmoc-Lys(2-chloro-Z)-OH (CAS 133970-31-7), a certified reference material (molecular formula C29H29ClN2O6, MW 537.00 g/mol) for analytical method development and quality control.

Structurally, Fmoc-Lys(2-chloro-Z)-OH (C29H29ClN2O6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 537.00 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
