Chemical Structure

287484-33-7 Fmoc-Asp-OH-15N L-Aspartic-15N acid, N-Fmoc derivative N-(9-Fluorenylmethoxycarbonyl)-L-aspartic-15N acid CAS 287484-33-7 chemical structure

Description

287484-33-7 Fmoc-Asp-OH-15N L-Aspartic-15N acid, N-Fmoc derivative N-(9-Fluorenylmethoxycarbonyl)-L-aspartic-15N acid (CAS 287484-33-7) is a high-purity analytical reference standard with the molecular formula C19H29[15N]O6 and a molecular weight of 368.43 g/mol.

The molecular framework of 287484-33-7 Fmoc-Asp-OH-15N L-Aspartic-15N acid, N-Fmoc derivative N-(9-Fluorenylmethoxycarbonyl)-L-aspartic-15N acid (C19H29[15N]O6) 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.
