CAS 99-76-3

Methylparaben

Description:

Methylparaben, with the CAS number 99-76-3, is a widely used preservative in cosmetics, pharmaceuticals, and food products. It is a member of the paraben family, which are esters of p-hydroxybenzoic acid. Methylparaben appears as a white crystalline powder or a colorless liquid and is soluble in alcohol and propylene glycol, but only slightly soluble in water. Its chemical formula is C8H8O3, and it has a molecular weight of approximately 152.15 g/mol. Methylparaben is known for its antimicrobial properties, effectively inhibiting the growth of bacteria and fungi, which helps extend the shelf life of products. It is generally recognized as safe by regulatory agencies when used within recommended concentrations. However, there has been some controversy regarding its potential endocrine-disrupting effects, leading to ongoing research and discussions about its safety in consumer products. Overall, methylparaben remains a popular choice for preserving various formulations due to its effectiveness and low toxicity profile.

Methyl 4-hydroxybenzoate - BP grade

CAS: 99-76-3

Methyl 4-hydroxybenzoate is an organic chemical compound that is used as a preservative in pharmaceuticals, cosmetics and other industrial applications. Methyl 4-hydroxybenzoate is also used in wastewater treatment plants as a coagulant to remove suspended solids. It is prepared by reacting benzoic acid with methanol. The methyl ester of 4-hydroxybenzoic acid has been shown to induce apoptosis in human cancer cells by inhibiting the ryanodine receptor and controlling the release of calcium from intracellular stores. This chemical also has genotoxic activity which may be due to the reaction between methyl 4-hydroxybenzoate and p-hydroxybenzoic acid. Methyl 4-hydroxybenzoate has a high boiling point, which makes it difficult to dissolve in water. This chemical can be analyzed using plasma mass spectrometry, which separates compounds by their molecular weight and ionizes them before

Methyl 4-hydroxybenzoate

CAS: 99-76-3

Methyl 4-hydroxybenzoate is an organic compound that has been used as a preservative in cosmetics, pharmaceuticals and food. It is a member of the group of compounds known as parabens. Methyl 4-hydroxybenzoate can be prepared by the reaction of p-hydroxybenzoic acid with methyl alcohol. The chemical formula for this substance is CH3CO2C6H4CH3. Methyl 4-hydoxybenzoate (MB) also shows genotoxic activity, which may be due to its ability to form intermolecular hydrogen bonding interactions with DNA or mRNA molecules. The genotoxicity of MB has been tested in vitro using bacterial strains and mammalian cells. MB also exhibits leukemia inhibitory factor (LIF) properties and may be useful for cancer therapy, although it needs more research to confirm this effect.
