In the realm of fine chemicals and pharmaceutical intermediates, a deep understanding of a compound's chemical properties is fundamental for successful application. 3-Oxocyclopentanecarboxylic Acid (CAS: 98-78-2) stands out as a molecule with a distinctive combination of functional groups that dictate its reactivity and utility. As a leading manufacturer and supplier of this chemical, we aim to provide clarity on its core chemical characteristics, empowering researchers and production teams to leverage its potential effectively.

The chemical formula of 3-Oxocyclopentanecarboxylic Acid is C6H8O3, with a molecular weight of 128.13 g/mol. Structurally, it is a cyclic compound featuring a five-membered carbon ring. The presence of a ketone group at the 3-position and a carboxylic acid group at the 1-position makes it a bifunctional molecule. This dual functionality is the source of its versatility in organic synthesis. The ketone group can undergo nucleophilic addition and reduction reactions, while the carboxylic acid group can participate in esterification, amidation, and decarboxylation reactions, among others. For chemists looking to buy this compound, understanding these inherent reactivities is key to designing effective synthetic strategies.

One of the most significant chemical properties influencing its application is its ability to undergo reduction, particularly hydrogenation. As noted in its applications, this compound readily converts to 3-hydroxycyclopentanecarboxylic acid when treated with reducing agents, a process that is fundamental for creating chiral centers or introducing hydroxyl functionalities into molecules. The melting point, typically recorded between 59-62°C, and its form as a white powder, further aid in its handling and analysis in a laboratory setting. These physical properties, coupled with its predictable chemical behavior, make it a reliable building block for complex molecular architectures.

The pKa value of 3-Oxocyclopentanecarboxylic Acid is approximately 4.62, indicating that it is a moderately acidic compound, typical for carboxylic acids. This acidity is relevant when considering reaction conditions or formulating solutions. Furthermore, its stability under standard storage conditions (inert atmosphere, room temperature) is a key advantage, ensuring that procured material retains its integrity over time. When sourcing from a manufacturer, understanding these properties is as important as confirming the purity and availability of CAS 98-78-2.

In summary, the chemical properties of 3-Oxocyclopentanecarboxylic Acid, stemming from its keto and carboxylic acid functionalities within a cyclopentane ring, render it an invaluable tool for chemists. Its predictable reactivity, particularly in hydrogenation, and favorable physical characteristics make it a highly sought-after intermediate for pharmaceutical synthesis and broader organic chemistry applications.
