Methyl paraben by Research Lab Fine Chem Industries is a high-grade reagent. Also known as Methyl 4-hydroxybenzoate or Methyl p-hydroxybenzoate and Nipagin, it is basically a methyl ester of p-hydroxybenzoic acid. It is usually available in the form of colourless crystals or while crystalline powder. It has limited solubility in water (2.5g/l at 25C) but is highly soluble in alcohol. It has a boiling point of 270.5C and a melting point between 125-128C. This reagent is stable under ordinary conditions, though one must avoid contact of heat or any flammable sources. Methyl paraben is incompatible with strong oxidizers. CAS No. 99-76-3 Quantity provided: 5kg/bottle Molecular formula: C8H8O3 Molecular weight: 152.149 g/mol Assay: Minimum 99%These reagents have a variety of applications in miscellaneous industries as they are highly compatible with a range of compounds. Methyl parabens are frequently used as antimicrobial agents or preservatives or flavouring agents. They are widely found in personal care products. Some of the reasons why they are commonly used include certain facts like, they have a low irritation potential and toxicity levels, and are effective against a wide spectrum of fungi and bacteria at low concentrations. Also, they are stable over a wide pH range and are biodegradable. One of the key facts is that, when two or more parabens are combined, their antimicrobial activity increases due to synergistic effect.
