In the landscape of fine chemical manufacturing, securing reliable supply chains for key intermediates is paramount. Pinacolone (CAS: 75-97-8), also known scientifically as 3,3-dimethylbutan-2-one, serves as a critical building block in the production of pharmaceuticals and agrochemicals. For process engineers and procurement specialists, understanding the nuanced specifications within a Certificate of Analysis (COA) is essential for maintaining reaction efficiency and regulatory compliance.
As a premier global manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. adheres to strict quality control metrics to ensure that every drum of tert-Butyl methyl ketone meets the demanding requirements of industrial synthesis. This article details the critical assay specifications, water content limits, and documentation standards required for successful scale-up.
Understanding Assay and Water Content
The primary metric for evaluating industrial purity in ketone intermediates is the assay percentage. For most commercial applications, a minimum assay of 97% is standard, though specific downstream processes may require tighter tolerances. Impurities such as residual acids or isomeric ketones can significantly impact reaction yields, particularly during asymmetric reductions or condensation reactions.
Water content is another critical parameter. Excess moisture can interfere with moisture-sensitive reagents, such as organometallics used in subsequent steps. Our production process utilizes advanced distillation columns to minimize water content, ensuring the technical grade material remains stable during storage and transport. When evaluating the synthesis route for your final API, starting with a low-water content intermediate reduces the need for additional drying steps, thereby optimizing overall process economics.

Regulatory compliance begins with documentation. A robust COA provides transparency regarding the chemical identity and purity profile of the batch. For Pinacolone, the COA should explicitly list gas chromatography (GC) results, water content (Karl Fischer), and physical constants such as boiling point and density.
Procurement teams should verify that the COA includes batch numbers corresponding to the physical shipment. This traceability is vital for audit readiness, especially when supplying regulated markets. At NINGBO INNO PHARMCHEM CO.,LTD., we maintain digital records for every production run, allowing clients to access historical data for trend analysis and quality verification.
Typical Quality Parameters
The following table outlines the standard specifications expected for high-quality 3,3-dimethylbutan-2-one intended for industrial use. These parameters align with international safety and quality standards.
| Parameter | Specification | Test Method |
|---|---|---|
| Assay (GC) | ≥ 97.0% | Gas Chromatography |
| Water Content | ≤ 0.5% | Karl Fischer Titration |
| Appearance | Colorless Liquid | Visual Inspection |
| Flash Point | 3°C | Closed Cup |
| UN Number | UN1993 | Transport Regulation |
| Hazard Class | 3 (Flammable Liquid) | GHS/ADR |
Batch Consistency Guarantees
For executives managing supply chain risk, batch-to-batch consistency is non-negotiable. Variations in purity can lead to failed validation batches in pharmaceutical production, resulting in significant financial loss. A reliable global manufacturer must demonstrate the capacity to produce tonnage quantities without deviation in quality profiles.
Our manufacturing facilities are equipped to handle large-volume orders, ensuring that the bulk price remains competitive without compromising on safety or purity. By controlling the entire manufacturing process from raw material sourcing to final packaging, we mitigate the risks associated with third-party traders. This vertical integration allows us to provide stable lead times and consistent COA specifications across multiple production cycles.
