paramenthane38diol

Paramenthane38diol, more commonly known in the chemical literature as p-menthane-3,8-diol (PMD), is an organic compound in the family of p-menthane derivatives. Its molecular formula is C10H18O2 and its molecular weight is about 170.26 g/mol. PMD is a diol with hydroxyl groups positioned at the 3 and 8 locations on the p-menthane skeleton, and it exists as several stereoisomers, typically supplied as a racemate in commercial products.

PMD occurs in nature in trace amounts within certain essential oils and can also be produced synthetically for industrial use. It is primarily valued as a fragrance ingredient in perfumery and as a flavor component in select food and beverage applications, where it contributes a citrus-menthol-like note. In addition to its direct use, PMD serves as a chemical intermediate in the synthesis of other aroma compounds.

In commercial practice, PMD is handled under standard chemical safety guidelines. It should be stored in a cool, dry place away from heat and oxidizers. Potential hazards include irritation to skin and eyes upon exposure, and inhalation risks if handled without appropriate controls. Regulatory oversight for PMD varies by country and product category; many jurisdictions regulate its use in cosmetics and fragrances, with permitted concentrations and usage contexts defined by regional authorities and industry guidelines.
