Product Name:L-Asparagine-15N2
English Name:L-Asparagine-15N2
CAS No.:748757-99-5
Aliases:L-2-Aminosuccinamic acid-15N2, 2-Amino-3-carbamoylpropanoic acid-15N2
Molecular Formula:C4H8N2O3 (H2^15NCOCH2CH(^15NH2)COOH)
Physical Properties:White crystalline powder; soluble in water (approx. 2.5 g/100 mL at 25°C), insoluble in ethanol and diethyl ether, soluble in dilute acids and bases. Melting point approx. 234-235°C (decomp.), specific rotation [α]D^20 -5.4° (c=1, H2O), pI approx. 5.41.
Uses:This product is a stable isotope 15N-labeled L-asparagine, commonly used as an isotopic tracer in protein and amino acid metabolism studies. It can serve as an internal standard in NMR spectroscopy, LC-MS/MS quantitative analysis, and metabolomics research, and is also widely applied in studies of enzymatic reaction mechanisms and nitrogen metabolic pathways.
Technical Specifications:
Purity: ≥99% (HPLC or elemental analysis)
15N isotopic enrichment: ≥98%
Appearance: white crystalline powder
Packaging: available from gram to kilogram scale, commonly 1 g, 5 g, 10 g
Storage: keep sealed and protected from light, refrigerated at 2-8°C
