Overview
Ethyl Violet Indicator is a synthetic dye primarily used in biological staining and as a pH indicator in laboratory applications. It belongs to the triarylmethane dye family and is known for its vivid color and sensitivity to pH changes. The compound is widely utilized in histology and microbiology for staining tissues and cells, aiding in microscopic analysis. Ethyl Violet is valued for its stability and ease of use in various staining protocols. It is typically supplied as a dark green to brown powder, which dissolves readily in water and alcohol. The dye's ability to change color based on pH makes it a versatile tool in chemical and biological research.
Physical and Chemical Properties
Ethyl Violet Indicator has a molecular formula of C31H42ClN3 and a molecular weight of 492.14 g/mol. It appears as a dark green to brown powder and is soluble in water and alcohol. The compound's solubility and stability make it suitable for use in aqueous and alcoholic solutions. The dye exhibits pH-dependent color changes, transitioning from yellow in acidic conditions to violet in alkaline environments. This property is particularly useful in titration experiments and biological staining, where visual indicators are required to monitor pH shifts or highlight cellular structures.
Main Applications
Ethyl Violet Indicator is primarily used in biological staining, particularly in histology and microbiology. It helps visualize cellular components under a microscope, aiding in the identification and study of tissues and microorganisms. The dye is also employed as a pH indicator in laboratory experiments, where it provides a visual cue for acidity or alkalinity. In addition to its scientific uses, Ethyl Violet has applications in educational settings, where it is used to demonstrate pH changes and staining techniques. Its versatility and reliability make it a staple in many laboratories and research facilities.
Safety and Storage
Ethyl Violet Indicator should be handled with care to avoid inhalation or skin contact. It is recommended to use the compound in well-ventilated areas and wear appropriate personal protective equipment, such as gloves and goggles. In case of contact, rinse thoroughly with water and seek medical advice if irritation persists. Storage conditions are critical to maintaining the dye's stability. Ethyl Violet should be kept in a cool, dry place away from direct light. Properly sealed containers are essential to prevent moisture absorption and degradation over time.
B2B Procurement Guide
When procuring Ethyl Violet Indicator, B2B buyers should verify the product's purity and CAS number to ensure quality. Supplier certifications and compliance with industry standards are also important considerations. The reference price range is approximately $50-$100 per 25g, depending on purity and supplier. Bulk purchases may offer cost savings, but buyers should assess storage capabilities to maintain product integrity. Reliable suppliers with a track record of delivering high-quality chemicals are preferred to minimize risks associated with substandard products.
