Description

(All-Z)-2-(Heptadeca-8,11-Dienyl)-4,5-Dihydro-1-Methyl-1-[2-[(Octadeca-9,12-Dienoyl)Amino]Ethyl]-1H-Imidazolium Methyl Sulphate is a high-purity, synthetic cationic lipid compound with a complex, unsaturated fatty acid-derived structure. This compound matters as a critical intermediate and functional material for advanced research and formulation development, particularly where specific molecular architecture and charge characteristics are required. It is primarily needed by pharmaceutical R&D, biotechnology, and specialty chemical synthesis sectors for applications in novel delivery systems and material science.

Application

• Lipid Nanoparticle (LNP) Formulation: As a structural or helper lipid component in the development of advanced drug delivery systems for nucleic acids (mRNA, siRNA).
• Biomimetic Membrane Research: Used in the study of membrane biophysics and the creation of synthetic vesicles or liposomes due to its unsaturated alkyl chains.
• Gene Transfection Reagent: Serves as a key cationic component in non-viral transfection reagents for introducing genetic material into cells in vitro.
• Specialty Surfactant / Emulsifier: Employed in formulations requiring a cationic surfactant with specific hydrophobic chain lengths and degrees of unsaturation.
• Chemical Synthesis Intermediate: Acts as a sophisticated building block for the synthesis of more complex ionic liquid compounds or functionalized lipids.
• Cosmetic Actives Delivery: Potential use in high-end cosmetic formulations for the encapsulation and targeted delivery of active ingredients.

Quality Control

Our (All-Z)-2-(Heptadeca-8,11-Dienyl)-4,5-Dihydro-1-Methyl-1-[2-[(Octadeca-9,12-Dienoyl)Amino]Ethyl]-1H-Imidazolium Methyl Sulphate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for all critical parameters are provided and available upon request, supporting compliance for research and cGMP-guided development work.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere. The material is hygroscopic (moisture-sensitive) and should be allowed to equilibrate to room temperature in a dry environment before opening to prevent condensation.
