Description

Tyrocidine CAS NO 8011-61-8 is a complex mixture of cyclic decapeptide antibiotics, primarily produced by the bacterium *Bacillus brevis*. This product is valued for its potent antimicrobial activity against a broad spectrum of Gram-positive bacteria. It serves as a critical raw material and research tool in the pharmaceutical and life sciences industries. Its unique mechanism of action, involving membrane disruption, makes it a subject of ongoing study for novel therapeutic applications.

Application

• Pharmaceutical Intermediates: Serves as a key starting material or intermediate in the synthesis of specialized antimicrobial agents and for research into new antibiotic classes.
• Microbiological Research: Used as a selective agent in culture media and in laboratory studies to investigate bacterial membrane physiology and mechanisms of antibiotic resistance.
• Biochemical Studies: Employed in research focusing on peptide-protein interactions, membrane biophysics, and the development of novel drug delivery systems.
• Reference Standard: Functions as a qualitative and quantitative standard in analytical methods development and quality control testing within pharmaceutical manufacturing.
• Topical Formulation Research: Explored for potential use in developing topical antiseptic or preservative formulations due to its localized antimicrobial effect.

Quality Control

Our Tyrocidine is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling. Certificates of Analysis (COA) documenting these results are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed in a low-humidity environment to maintain stability and prevent degradation.
