Application Overview

As a highly diffusive and substantive aldehyde, 2-Methylundecanal is a versatile tool for perfumers across diverse product platforms:

• Fine Fragrances: It is a classic component in the construction of the Aldehydic Floral fragrance family (e.g., Chanel No. 5). It provides lift, radiance, and a champagne-like effervescence to top and heart notes, while also extending tenacity.

• Soaps and Detergents: Its excellent stability and tenacity make it invaluable in functional products. It helps create a powerful, fresh 'out-of-the-pack' or 'clean laundry' note in powdered detergents, liquid soaps, and cleaners.

• Cosmetics and Personal Care: Used in small amounts to enhance the perceived freshness and quality of creams, lotions, and deodorants, contributing to the overall clean and waxy-citrus accord.

• Flavoring: Though primarily a fragrance material, it is sometimes used in trace quantities to achieve specific citrus or fruity nuances in flavor formulations (pending regulatory status).

• Boosting Agent: It is often used to boost the performance of more expensive or less stable citrus oils, lending complexity and longevity to the entire blend.

Why Choose Aure Chemical for 2-Methylundecanal?

Aure Chemical offers 2-Methylundecanal (CAS 110-41-8) with stringent quality controls that ensure stability, potency, and compliance for the most sensitive formulations.

• Minimization of Acid & Peroxide: Aldehydes are prone to oxidation into corresponding acids, which can ruin a fragrance. Our production includes advanced inert gas blanketing and frequent quality checks to guarantee extremely low acid and peroxide values, maximizing the product's lifespan and preventing batch deterioration.

• Certified Enantiomeric Integrity: 2-Methylundecanal is a chiral molecule. We offer certified grades with controlled enantiomeric ratios, ensuring a consistent and defined odor profile that prevents the subtle olfactory shifts that can occur with poorly controlled racemic mixtures.

• Airtight, Light-Filtering Packaging: To combat polymerization and oxidation, our Aldehyde C-12 MNA is exclusively packaged in amber glass or stainless steel vessels with minimal headspace. This light-filtering and airtight solution ensures the volatile compound maintains its powerful, pure odor from our warehouse to your compounding facility.

• Integrated Fragrance Compliance: Alongside Kosher and Halal certification, we proactively provide up-to-date IFRA (International Fragrance Association) documentation, ensuring that the concentration limits and safety data for this potent compound are readily available for your final product formulation.
