Chemical Structure
Description
Fmoc-Aph(D-Hor)-OH (CAS CATO-CPTD789021), molecular formula C29H26N4O7 and molecular weight 542.54 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C29H26N4O7, Fmoc-Aph(D-Hor)-OH contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 542.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
