- 中文别名
- 亮氨酸-13C6；L-亮氨酸(13C6)；13C标记L-亮氨酸
- 英文名称
- L-Leucine-13C6
- 分子式
- C6H13NO2
- 分子量
- 137.13（六个13C取代天然碳），化学纯度≥98%
- 所属类别
- 试剂实验设备
- 物化性质
- 白色结晶或结晶性粉末，溶于水，微溶于乙醇，不溶于乙醚。熔点约293°C（分解）。本品为六个碳原子全部被13C稳定同位素标记的L-亮氨酸，同位素标记不影响其物理化学性质，但分子量增至137.13。
- 外观
- 白色结晶粉末，干燥失重≤0.5%
- 储存条件
- 2-8°C密封避光保存，保质期24个月
English description（英文原文，共 1207 字符）
Product Name:L-Leucine-13C6
English Name:L-Leucine-13C6
CAS No.:201740-84-3
Aliases:Leucine-13C6, L-Leucine (13C6), 13C-labeled L-Leucine
Molecular Formula:C6H13NO2
Physical Properties:White crystalline powder, soluble in water, slightly soluble in ethanol, insoluble in diethyl ether. Melting point approximately 293°C (decomposition). All six carbon atoms are replaced by 13C stable isotope labels; isotopic labeling does not alter its physicochemical properties, but the molecular weight increases to 137.13.
Uses:Used as a stable isotope-labeled standard, widely applied in metabolomics, proteomics, and metabolic pathway research in living organisms. Serves as an internal standard for mass spectrometry analysis and nuclear magnetic resonance detection, and is also used in amino acid metabolic kinetics studies.
Technical Specifications:
Molecular weight: 137.13 (six 13C instead of natural carbon), chemical purity ≥98%
Isotopic abundance: 13C ≥99%, optical purity (L-configuration) ≥99%
Appearance: white crystalline powder, loss on drying ≤0.5%
Storage: sealed and stored away from light at 2-8°C, shelf life 24 months
Packaging: 100mg, 500mg, 1g in routine, custom packaging available
