Caprylic/Capric Acid Extra Pure

Whatsapp Order

Caprylic/Capric Acid Extra Pure is a high-purity blend of medium-chain saturated fatty acids—primarily octanoic (caprylic) and decanoic (capric) acids—used in laboratory environments for studying lipid chemistry, esterification, and antimicrobial properties. Its dual-chain composition makes it valuable for investigating emulsion systems, fatty acid metabolism, and as a reference standard in chromatographic analysis. This acid mixture is also employed in the synthesis of esters, surfactants, and as a model compound in solubility and partition coefficient experiments. The extra pure grade ensures minimal contamination, supporting consistent and accurate results in biochemical and organic chemistry applications. It should be stored in a cool, dry place in tightly sealed containers to maintain stability and prevent oxidation.

Description

Primary Uses
Lipid and Fatty Acid Analysis

Frequently used in chromatographic studies (e.g., GC, HPLC) as a standard or test compound for analyzing medium-chain fatty acids.

Biochemical and Nutritional Research

Studied for its metabolic behavior and role in energy metabolism, especially in research related to ketogenic diets or MCT (Medium Chain Triglyceride) formulations.

Antimicrobial Activity Testing

Used in microbiology labs to study its antibacterial and antifungal properties, especially against Candida species and Gram-positive bacteria.

Solubility and Emulsification Studies

Employed in emulsion experiments to examine miscibility, phase behavior, and stability of fatty acid-based systems.

Secondary Uses
Cosmetic and Dermatological Research

Studied as a component in topical formulations or for its role in skin absorption and carrier functions in cosmetic chemistry.

Model Compound in Esterification Reactions

Serves as a representative fatty acid in organic synthesis labs to explore esterification, transesterification, and saponification mechanisms.

pH and Buffering Capacity Experiments

Investigated in analytical setups for its acid dissociation behavior and buffering properties in various solvent systems.

Toxicological Studies

Sometimes used in in vitro studies to evaluate cellular responses or irritation potential of fatty acids.
