Chemical Structure

H-D-Asp(OtBu)-OH CAS 64960-75-4 chemical structure

Description

H-D-Asp(OtBu)-OH (CAS 64960-75-4) is a high-purity analytical reference standard with the molecular formula C8H15NO4 and a molecular weight of 189.21 g/mol.

The molecular framework of H-D-Asp(OtBu)-OH (C8H15NO4) is characterized by an amino-acid-derived structure, 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.

CATO manufactures H-D-Asp(OtBu)-OH under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
