L-Argininosuccinic acid-¹³C₆,¹⁵N₄ barium salt dihydrate is an isotopically labeled arginine-derived dicarboxylic amino acid derivative in which the argininosuccinic acid framework bears ¹³C enrichment at six carbon positions and ¹⁵N enrichment at four nitrogen positions, forming a barium salt with two waters of crystallization. The molecule contains both amino and carboxyl functional groups characteristic of argininosuccinic acid, with the side-chain guanidinium-type nitrogen environment retained but rendered isotopically traceable for spectroscopic and mass-based detection. As a labeled salt form, it is used as a substrate or reference material in isotopic tracing, quantitative analytical method development, and structure-mass spectrometry studies that require incorporation of defined ¹³C/¹⁵N labeling patterns into downstream amino acid or peptide-related analytical workflows.
