Chemical Structure
Description
The occurrence of Aspartic Acid Hydrate - API Standards is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Aspartic Acid Hydrate - API Standards (CAS 99108-34-6) is a high-purity analytical reference standard with the molecular formula C4H7NO4H2O and a molecular weight of 151.12 g/mol.
The molecular framework of Aspartic Acid Hydrate - API Standards (C4H7NO4H2O) is characterized by a carbohydrate-derived structure, an amide group. 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.
As a certified reference material (CRM), Aspartic Acid Hydrate - API Standards meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
