In the demanding field of chemical synthesis, particularly for pharmaceutical applications, a thorough understanding of intermediate specifications is crucial. 2-Chlorobutyric Acid, identified by CAS number 4170-24-5, is a prime example of such an intermediate, with its primary role being in the synthesis of Levetiracetam, an essential antiepileptic drug. Manufacturers and researchers who intend to buy 2-Chlorobutyric Acid must pay close attention to its detailed technical specifications to ensure optimal results.

The appearance of 2-Chlorobutyric Acid is typically described as a light yellow liquid. This visual characteristic is the first step in verifying product identity and quality. Beyond appearance, its physical and chemical properties are precisely defined. The density is recorded as 1.19, and the boiling point is noted between 90-92°C at 12 mmHg, indicating its behavior under varying conditions. The flash point of 76.7°C is important for safety protocols during handling and storage, while the refractive index of 1.439 is a key metric for quality assurance and purity assessment. These precise measurements are standard from any reputable 2-chlorobutyric acid supplier.

The most critical specification for any pharmaceutical intermediate is its purity. 2-Chlorobutyric Acid typically boasts a purity of ≥99%. Furthermore, stringent controls are placed on its composition, with moisture content and impurities each kept below 0.3%. This high level of purity is non-negotiable for its use as a Levetiracetam synthesis intermediate, as any contaminants could compromise the final drug's efficacy or safety profile. Companies that need to buy 2-chlorobutyric acid should always prioritize suppliers who can consistently provide material meeting these exacting standards.

Packaging and storage are also integral to maintaining the quality of 2-Chlorobutyric Acid. It is commonly supplied in 25kg cardboard drums, though custom packaging is often available. Proper storage in a cool, dry, well-closed container, away from moisture and strong light or heat, is essential to preserve its chemical integrity. For businesses that require this compound, selecting a high purity 2-chlorobutyric acid supplier that also provides guidance on storage and handling ensures the intermediate remains fit for purpose throughout its lifecycle.
