Product Overview
Description:
Arachidonic acid 1,2,3,4,5-13C is an isotopically enriched essential polyunsaturated fatty acid containing carbon-13 atoms at positions 1, 2, 3, 4, and 5. This labeled lipid acts as a high-precision tracer for mass spectrometry workflows, allowing investigators to track the receptor-stimulated release, structural membrane turnover, and metabolic processing of free arachidonate into eicosanoid second messengers.
Labeling:
Stable isotope-labeled
Synonyms:
5Z,8Z,11Z,14Z-eicosatetraenoic-1,2,3,4,5-13C5 acid; AA 1,2,3,4,5-13C; FA 20:4-13C
Formula:
C1513C5H32O2
Formula Weight:
309.4
Specification
Solubility in DMSO:
100 mg/mL
Solubility in DMF:
100 mg/mL
Solubility in Other Solvents:
Na2CO3: 1 mg/mL

Storage at -20°C.
Applications:
Arachidonic acid 1,2,3,4,5-13C serves as a stable isotope-labeled internal standard for quantitative analysis of arachidonic acid. It supports isotope dilution LC-MS/MS, analytical calibration, signal normalization, method validation, and accurate quantification of arachidonic acid and related lipid mediators.
