Chemical Structure
Description
(R)-methyl 2-((R)-2-(benzyloxycarbonylamino)propanamido)propanoate 19914-26-2 Z-D-Ala-D-Ala-OMe (CAS 19914-26-2), molecular formula C15H20N2O5 and molecular weight 308.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-methyl 2-((R)-2-(benzyloxycarbonylamino)propanamido)propanoate 19914-26-2 Z-D-Ala-D-Ala-OMe (C15H20N2O5) is characterized by a flavonoid 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (R)-methyl 2-((R)-2-(benzyloxycarbonylamino)propanamido)propanoate 19914-26-2 Z-D-Ala-D-Ala-OMe 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.
