Your 2-Methylbutyric Acid Partner – Superior Supply from Aure Chemical
2-Methylbutyric Acid (2-MBA), also known as α-Methylbutyric acid (CAS 116-53-0), is a short-chain branched fatty acid that is naturally found in various dairy products, fruits, and volatile components of coffee. It is a colorless liquid known for its sharp, sour, pungent, and cheesy odor, often described as a rancid butter or fermented milk note at high concentrations. Despite its strong character, 2-MBA is indispensable in low concentrations for building authentic, complex dairy, butter, and savory cheese flavor profiles, and for contributing to diffusive, animalic notes in fragrances. Aure Chemical guarantees a high-purity product with full Halal certification.

Application Overview
2-Methylbutyric Acid's powerful character is utilized in highly specialized applications where authentic dairy, savory, or animalic notes are required:
Dairy Flavoring: It is a critical component in building realistic, cooked butter, cream, milk, and savory cheese flavor profiles (e.g., Cheddar, Parmesan). Used in snack seasonings, cheese powders, and baked goods.
Savory and Meat Flavors: Used in minute traces to provide an authentic fermented, deep, or slightly animalic undertone in beef, lamb, and other savory reaction flavors.
Fruity and Coffee Flavors: In combination with esters, it helps simulate the complex, slightly fermented, or 'sweaty' character of certain tropical fruits or the rich aroma of roasted coffee and cocoa.
Fine Fragrances: In perfumery, it is used very sparingly to create animalic, leather, and deep mossy accords. It provides a challenging yet rewarding fermented or 'dirty' undertone that adds immense depth and realism to certain niche and oriental compositions.
Why Choose Aure Chemical for 2-Methylbutyric Acid?
Aure Chemical offers 2-Methylbutyric Acid (CAS 116-53-0) with unique quality control measures essential for such a potent, regulated chemical.
High Isomer Purity (Chiral Control): 2-MBA is a chiral molecule. We offer grades with optimized control over the chiral center, ensuring the highest percentage of the desired enantiomer. This is critical as the olfactory and flavor profile can vary dramatically between the (R) and (S) forms, providing the most authentic, targeted profile.
Traceability and Ethical Sourcing: Our 2-Methylbutyric Acid synthesis is built upon a fully documented and audited supply chain, ensuring full Halal compliance and guaranteeing that no prohibited substances were used at any stage of the process, from starting materials to packaging.
Safety and Handling Protocols: Given its corrosive classification and powerful odor, we utilize specialized, low-volume dispensing equipment and dedicated negative-pressure ventilation systems. This minimizes operator exposure and ensures safer, high-purity transfer into inert gas-blanketed containers.
Precise Dilution and Usage Guidance: Recognizing the extremely low dosage required, we offer pre-diluted stock solutions (e.g., 1% in PG), manufactured in-house under strict quality control. This allows flavorists and perfumers to handle the material safely and dose it accurately, minimizing waste and formulation errors.
