Description

L-Aspartic Acid-2-13C is a stable isotope-labeled analog of the essential amino acid L-aspartic acid, specifically enriched with carbon-13 at the 2-position. This high-purity labeled compound is critical for advanced research requiring precise metabolic pathway tracing and quantitative analysis. It is primarily utilized by research institutions, pharmaceutical developers, and diagnostic manufacturers in the fields of nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), and metabolic flux analysis.

Application

• Metabolic Research & Flux Analysis: As a tracer to study the citric acid cycle (Krebs cycle), amino acid metabolism, and urea cycle dynamics in biological systems.
• Biomedical & Pharmaceutical Research: Used in the development and testing of new drugs, particularly those targeting metabolic disorders or neurological pathways where aspartate is a key neurotransmitter.
• Analytical Chemistry Standard: Serves as an internal standard for the accurate quantification of L-aspartic acid in complex matrices using LC-MS or GC-MS, improving analytical precision.
• Nutritional Science Studies: Employed in research investigating protein synthesis, amino acid bioavailability, and specialized nutritional formulations.
• Isotope Labeling in Synthesis: Used as a building block for the synthesis of more complex 13C-labeled peptides, proteins, or other bioactive molecules for research purposes.

Quality Control

Our L-Aspartic Acid-2-13C is manufactured under strict quality systems to ensure exceptional isotopic and chemical purity, essential for sensitive research applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic enrichment (atom % 13C), chemical purity (by HPLC), chiral purity, and residual solvent content. We adhere to rigorous in-house standards designed for research-grade biochemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which can affect stability and weighing accuracy.
