For procurement professionals and technical teams evaluating chemical suppliers, understanding and verifying product specifications is paramount. 2-Ethylhexanol (CAS 104-76-7), a critical industrial chemical, demands strict quality control to ensure its efficacy in diverse applications, from plasticizers to solvents. As a leading manufacturer and supplier, we emphasize the importance of these quality parameters and how they contribute to your success.

The cornerstone specification for 2-Ethylhexanol is its purity. Typically, industrial-grade 2-Ethylhexanol is supplied at a minimum purity of 99.5%. This high level of purity is essential, especially when it is used as a raw material for synthesizing esters like DOP and DOTP, where even minor impurities can affect reaction yields and the performance characteristics of the final plasticizers. Buyers should always seek suppliers who can provide Certificates of Analysis (CoA) detailing the purity and other key parameters for each batch.

Appearance is another straightforward yet critical indicator of quality. High-grade 2-Ethylhexanol is a clear, colorless liquid. Any deviation, such as turbidity or discoloration, could suggest contamination or degradation. Its characteristic odor, while subjective, is also a notable feature that should be consistent with the expected profile of pure 2-Ethylhexanol.

Beyond general purity and appearance, specific impurity levels are closely monitored. Key parameters to scrutinize when you decide to buy 2-Ethylhexanol include:

1. Water Content: Low moisture content (typically ≤ 0.10%) is vital. Excess water can interfere with esterification reactions and affect product stability.

2. Acidity: Measured as acetic acid, the acidity should be minimal (≤ 0.01%). High acidity can indicate degradation or contamination and can catalyze unwanted side reactions.

3. Carbonyl Compounds: Particularly those based on 2-Ethylhexanal, these should be present at very low levels (≤ 0.05%). Their presence can impact odor and reactivity.

4. Sulfuric Acid Color Test: This test, often reported with a Platinum-Cobalt scale number (≤ 25), indicates the overall color purity and absence of trace contaminants that might be detected by this method.

For buyers sourcing 2-Ethylhexanol from China manufacturers, these specifications are routinely managed and reported. Reputable suppliers will provide detailed test results that align with international standards. Understanding these quality benchmarks empowers you to make informed decisions and select a supplier that consistently delivers material meeting your exact requirements. Partnering with a manufacturer that prioritizes stringent quality control ensures that your downstream processes benefit from a reliable and high-performance chemical intermediate.
