5-Chloro-2-Pentanone Ethylene Ketal (CAS 5978-08-5) Supplier – High-Purity Organic Synthesis Intermediate from Finetech Industry Limited
1. Product Overview
5-Chloro-2-pentanone ethylene ketal (CAS 5978-08-5) is a chlorinated cyclic ketal compound used as a building block in organic synthesis and chemical research. It is also known by its systematic name, 2-(3-chloropropyl)-2-methyl-1,3-dioxolane.
The molecule contains two important structural features: a terminal chloroalkyl group and a cyclic ethylene ketal. The ketal functionality serves as a protected form of a carbonyl group, while the terminal chlorine provides a reactive site for further chemical transformations. This combination makes the compound useful for synthetic strategies that require controlled functional-group manipulation.
Finetech Industry Limited supplies 5-Chloro-2-pentanone Ethylene Ketal, catalog number FT-0635926, with an assay of ≥97%. It is suitable for organic synthesis development, intermediate preparation, and laboratory-scale research, with larger quantities available for customers requiring scale-up supply.

3. Chemical Characteristics and Structural Features
5-Chloro-2-pentanone Ethylene Ketal is a cyclic ketal containing a 1,3-dioxolane ring attached to a three-carbon chain terminating in a chlorine atom. Its molecular structure provides complementary reactivity that can be useful in multi-step organic synthesis.
Ketal-protected carbonyl functionality
The cyclic ethylene ketal masks the original ketone functionality. This protection can help maintain the carbonyl-derived center in a less reactive form during selected synthetic transformations. Under suitable acidic hydrolysis conditions, the ketal can be converted back to its corresponding carbonyl functionality.
Terminal chloroalkyl functionality
The terminal carbon–chlorine bond provides a potential site for nucleophilic substitution. Depending on the reaction conditions and selected nucleophile, this functional group can be used to introduce different substituents into a molecular framework.
Complementary functional-group reactivity
The combination of a protected carbonyl group and a terminal halide offers synthetic flexibility. Researchers can investigate transformations at the chloroalkyl chain while retaining the ketal protection, followed by subsequent deprotection when the carbonyl functionality is required.
4. Research Applications in Organic Synthesis
4.1 Preparation of Functionalized Organic Intermediates
The terminal chloroalkyl group makes this compound a useful starting material for exploring nucleophilic substitution reactions. It can support the preparation of functionalized intermediates containing oxygen-, nitrogen-, or sulfur-based substituents, depending on the reaction system.
These transformations are relevant to the development of substituted organic molecules and the preparation of intermediates for further synthetic steps.
4.2 Ketal Protection Strategies
The ethylene ketal group provides a protected carbonyl equivalent for synthetic sequences involving multiple reactive functional groups.
In organic synthesis research, carbonyl protection can help reduce unwanted reactions at the ketone-derived center while other parts of the molecule are modified. The ketal can subsequently be removed under suitable conditions to regenerate the carbonyl functionality.
4.3 Multi-Step Organic Synthesis
The two functional elements of 5-Chloro-2-pentanone Ethylene Ketal offer opportunities for sequential transformations.
Researchers can investigate modification of the terminal chloroalkyl group, retain the cyclic ketal during selected reaction steps, and then carry out ketal deprotection when required. This approach can be useful in the preparation of more complex intermediates and functionalized molecular structures.
4.4 Heterocyclic and Fine Chemical Research
Functionalized alkyl halides and protected carbonyl compounds are useful building blocks in the development of synthetic routes toward structurally diverse molecules.
5-Chloro-2-pentanone Ethylene Ketal may therefore be considered in route-design studies involving heterocyclic compounds, fine chemicals, and specialized organic intermediates. Its suitability for a particular target structure should be evaluated through reaction development and experimental validation.
4.5 Process Development and Scale-Up Studies
For chemical manufacturers and process development teams, reliable access to an intermediate is important when moving from initial reaction screening to larger-scale synthesis.
The availability of 5-Chloro-2-pentanone Ethylene Ketal in multiple packaging sizes supports different stages of research, including preliminary evaluation, reaction optimization, and larger-scale process studies.
