For procurement managers and R&D scientists in the chemical, flavor, and fragrance industries, a thorough understanding of product specifications is critical when looking to buy 2-Octanone (CAS 111-13-7). Ensuring the material meets exact requirements guarantees product performance, regulatory compliance, and efficient manufacturing processes. This guide outlines the essential specifications to verify with your manufacturer or supplier.

Key Specifications to Verify for 2-Octanone

When you are ready to purchase 2-Octanone, several key parameters should be at the forefront of your checklist:

1. Purity (Assay): This is arguably the most critical specification. For most applications, especially in fragrances and flavors, a high purity level is essential. Manufacturers typically list this as an 'Assay' and commonly offer 2-Octanone with a purity of ≥99%. Lower purity grades might be acceptable for some industrial solvent uses, but always confirm this with your supplier.
2. Appearance: The visual appearance of 2-Octanone is a standard quality indicator. It should consistently be a 'colorless liquid'. Any deviation from this description, such as cloudiness or discoloration, could indicate contamination or degradation.
3. Water Content: For many applications, minimizing water content is important. Suppliers usually provide a maximum limit for water content, often specified as '≤0.2%'.
4. Acidity: The presence of free acids can affect product stability and reactivity. The acidity is typically measured and reported as a maximum percentage of acetic acid, e.g., '≤0.05% (as acetic acid)'.

CAS Number and Molecular Information

The CAS Number, 111-13-7, is the universal identifier for 2-Octanone. Always cross-reference this number with your order and the supplier's documentation. Additional helpful information from manufacturers includes the molecular formula (C8H16O) and molecular weight (128.21 g/mol), which are standard identifiers in chemical procurement.

Regulatory Compliance and Safety Data

Beyond the chemical properties, ensure your supplier can provide necessary safety data, such as a comprehensive Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS). This document details handling, storage, hazard information, and first-aid measures. Depending on your end-use, you may also need to confirm compliance with specific industry regulations, such as FEMA GRAS status for flavor applications. When you buy 2-Octanone, understanding these aspects protects your operations and end-users.

By meticulously reviewing these specifications before you buy, you ensure that the 2-Octanone you procure from any manufacturer or supplier meets your exact requirements, paving the way for successful product development and manufacturing.
