Phenol 10% 100 ml

What phenol 10% solution is actually used for beyond textbook chemistry

Phenol has remained one of the most consistently demanded chemical compounds worldwide for well over a century, valued for its antiseptic, denaturing and dissolving properties. This 10% solution in a 100 ml pack belongs to the Chemical Raw Materials section and is a practical format for laboratories, research testing and small-scale technical work where large industrial volumes are unnecessary and unwanted.

Globally, the strongest demand for phenol comes not from cosmetics but from analytical chemistry, microbiology, veterinary practice and the production of polymer materials. In laboratory settings, diluted phenol solutions are traditionally used for preservation of biological specimens, as a component of disinfecting mixtures for instruments and surfaces, and as a reagent in certain protein and carbohydrate determination methods. In industry, phenol at various concentrations serves as feedstock for phenol-formaldehyde resins, antiseptic formulations, and wood or textile treatment agents. In veterinary and agricultural settings, dilute phenol solutions have historically been applied for disinfecting premises and equipment.

Working with phenol requires attention to its chemical reactivity: it can interact with alkalis, oxidizers and certain metals, so any mixing with other reagents should follow verified protocols with strict attention to the temperature range specified for the given procedure. In chemical laboratories, phenol is frequently used alongside other reagents for comparative testing or sequential sample processing stages — for instance together with thiourea, widely used in analytical chemistry and electroplating, or alongside manganese compounds such as manganese oxide (tetraoxide) and manganese sulfate, which are relevant in metallurgy, fertilizer production and chemical synthesis.

Phenol solution is typically introduced into working mixtures at room temperature or with slight warming to around 30-40 degrees Celsius when the protocol requires it, since higher temperatures accelerate evaporation and reduce dosing accuracy. Dosage depends heavily on the intended task: disinfecting solutions commonly use a 1 to 5 percent concentration of active substance in the final mixture, while laboratory preservation blends follow different ratios set by the specific research protocol. Store the phenol solution in a tightly sealed dark glass container, in a dry, cool place away from open flame, direct sunlight and food products, always using appropriate personal protective equipment during handling.

The 100 ml pack size is well suited for small analytical batches, teaching purposes in chemistry and biology courses, and workshops where the reagent is needed occasionally and in limited quantity, without the need to store large reserves of the substance.

Working antiseptic solution for laboratory surface treatment

Phenol 10% - 25 ml

Distilled water - 165 ml

Technical ethanol - 10 ml

Combine room-temperature distilled water with the phenol solution in a clean glass container, stirring gently with a glass rod until fully uniform. Add the technical ethanol in small portions while continuing to stir for another two to three minutes until the mixture becomes clear and homogeneous. Transfer the finished solution into a tightly sealed container, label it with the preparation date, and use it for wiping down laboratory glassware and metal tools, always wearing gloves and following standard chemical handling precautions.
