  • Applications

    4-Methylbenzaldehyde propyleneglycol acetal (CAS 58244-29-4) is primarily used as an aldehyde-protecting acetal in organic synthesis, enabling selective transformations by masking the reactive benzaldehyde function. In fragrance and cosmetic applications, it serves as a fragrance intermediate and aroma component with an almond-like note, and may also function as a minor fixative or building block for more complex odorants. It is also employed as an intermediate in the synthesis of other p-tolyl-derived fragrance chemicals, and may be evaluated for use in flavor/fragrance formulations in R&D settings, subject to regulatory constraints. In specialized industrial contexts, it can be handled as a specialty chemical for formulation development and as a synthetic intermediate in polymer or resin chemistry where aldehyde masking is advantageous.
