Description

Tetracosanoic Acid Trimethylsilyl Ester is a high-purity, derivatized fatty acid ester used as a critical analytical standard and synthetic intermediate. Its primary value lies in its role for precise quantification and identification in chromatographic analysis, particularly for complex lipid mixtures. This compound is essential for researchers and quality control laboratories in the pharmaceutical, biotechnology, and advanced materials sectors where accurate lipid profiling is required.

Application

• Gas Chromatography (GC) and GC-Mass Spectrometry (GC-MS) Standard: Used as a reference compound for the identification and quantification of very long-chain fatty acids (VLCFAs) and their derivatives in biological and synthetic samples.
• Lipidomics Research: Serves as a key derivatization product for the analysis of tetracosanoic acid (lignoceric acid) in metabolic studies, biomarker discovery, and disease research.
• Synthetic Intermediate: Employed in organic synthesis for the preparation of more complex lipid analogs, surfactants, and specialty polymers where a protected carboxylic acid group is needed.
• Quality Control in Pharmaceutical Manufacturing: Acts as a system suitability test compound or an impurity reference standard in the analysis of lipid-based drug products and excipients.
• Material Science: Utilized in the development and analysis of advanced coatings, lubricants, and waxes where specific fatty acid profiles are critical to performance.

Quality Control

Our Tetracosanoic Acid Trimethylsilyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity assessment (GC/FID, GC-MS) and identity confirmation (IR, NMR), to ensure it meets the high standards required for analytical and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as specified on the label or COA. This product is hygroscopic (moisture-sensitive). Allow the sealed container to reach ambient temperature before opening to minimize condensation and moisture ingress.
