Chemical Structure

DL-Aspartic acid-d3 CAS 14341-75-4 chemical structure

Description

As a certified reference material (CRM), DL-Aspartic acid-d3 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.

DL-Aspartic acid-d3 (CAS 14341-75-4), molecular formula C4H4D3NO4 and molecular weight 136.12 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, DL-Aspartic acid-d3 (C4H4D3NO4) contains deuterium isotope labeling, a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 136.12 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
