Product Overview
o-Tolidine reagent LR is a high-quality laboratory chemical designed for precise chlorine detection and analytical applications. This liquid reagent, classified under Laboratory Reagent (LR) grade, ensures reliable performance in qualitative and quantitative testing procedures. Its chemical structure, 4,4′-diamino-3,3′-dimethyldiphenylmethane, reacts selectively with free chlorine, producing a yellow coloration that aids in accurate measurement. The reagent is formulated to meet stringent laboratory standards, offering consistency and reproducibility in results. Its stability under standard storage conditions makes it a preferred choice for routine lab work. The LR grade designation guarantees a purity level suitable for most general laboratory applications, ensuring minimal interference from impurities. Whether used in titration methods or colorimetric analysis, this reagent provides clear, interpretable results. The 500 ml packaging offers an optimal balance between quantity and shelf life, reducing the need for frequent replenishment while maintaining freshness.
FAQs
1. What is the shelf life of o-Tolidine reagent LR when stored properly?
The reagent typically maintains its effectiveness for 12-24 months when stored in a cool, dark place with the container tightly sealed. Always check the manufacturer’s expiration date on the label for precise guidance.
2. Can this reagent be used for detecting chlorine in water samples?
Yes, o-Tolidine reagent LR is specifically formulated for chlorine detection in water samples, producing a measurable color change that correlates with chlorine concentration.
3. What safety precautions should be taken while handling this chemical?
Always wear appropriate personal protective equipment including gloves, goggles, and lab coat. Work in a well-ventilated area or under a fume hood, as the reagent may release harmful vapors.
4. How should I dispose of unused or expired o-Tolidine reagent?
Follow your institution’s chemical waste disposal protocols. Typically, this involves collecting in a designated hazardous waste container and arranging for proper disposal through authorized waste management services.
5. What alternatives exist if o-Tolidine reagent is unavailable?
DPD (N,N-diethyl-p-phenylenediamine) reagent is a common alternative for chlorine testing, offering similar colorimetric detection properties with potentially different sensitivity ranges.
