Dimidium bromide 112130 Merck

Product Overview: Dimidium Bromide Code 112130 Merck

Dimidium bromide, available under product catalog code 112130 from Merck KGaA, is a specialized cationic phenanthridinium dye with extensive utility in analytical biochemistry and surfactant quantification. Known systematically as 3,8-Diamino-5-methyl-6-phenylphenanthridinium bromide, this fluorogenic compound is identified by CAS Number 518-67-2, EC Number 208-256-7, Hill Formula C20H18BrN3, Molar Mass 380.31 g/mol, HS Code 29339999, and Quality Level MQ200. Its planar heteroaromatic core enables precise intercalation into nucleic acid base pairs, resulting in notable fluorescent emission changes. Additionally, dimidium bromide serves as an indispensable colorimetric reagent in classical two-phase mixed indicator titrations, commonly referred to as the Epton or ISO method, for evaluating anionic and cationic active ingredients across laundry detergents, industrial cleansers, and cosmetic formulations.

Safety Information and First Aid Guidelines

Dimidium bromide is classified as an irritant. Standard biochemical laboratory safety protocols must be followed to avoid unintended exposure.

Personal protective equipment including laboratory coats, nitrile gloves, and side-shield safety glasses must be worn during all handling procedures.

Avoid airborne dust formation and ensure weighing procedures occur in well-ventilated areas or dedicated fume cabinets.

After Inhalation: Provide the affected person with fresh air. Ensure comfortable respiration.

After Skin Contact: Remove all contaminated clothing immediately. Rinse skin thoroughly with plenty of running water or under a safety shower.

After Eye Contact: Flush eyes gently with abundant water for several minutes. Remove contact lenses if easy to do and continue thorough rinsing.

After Swallowing: Never induce vomiting. Rinse mouth with water and have the victim drink up to two glasses of water. Seek medical advice if irritation or discomfort persists.

Specialized Applications in Detergent and Analytical Chemistry

The analytical relevance of Merck code 112130 lies primarily in its performance as an indicator alongside acid blue dyes in the two-phase titration of surfactants. It reacts with anionic surfactants to produce a distinctive pink-to-red organic phase, which sharply transitions to blue upon completion of titrations with quaternary ammonium reagents. Moreover, the fluorimetric sensitivity of dimidium bromide makes it a valuable molecular probe for monitoring conformational transitions, DNA-protein binding dynamics, and cellular uptake mechanisms in modern biochemical research.
