2-Furaldehyde diethyl acetal (CAS No.: 13529-27-6): Product Profile, Parameter and Industrial Application Analysis

1. Product Overview

2‑Furaldehyde diethyl acetal is a valuable furan‑based heterocyclic building block, widely applied in organic synthesis, pharmaceutical R&D and flavor‑fragrance development.

With the acetal group on furan ring, this compound offers reliable aldehyde‑group protection for hydrolysis, cross‑coupling and acetal‑exchange reactions. It is used only for laboratory‑scale research and intermediate preparation, not as finished API or flavor product, and plays a key role in constructing furan‑containing bio‑active and flavor‑related molecules.

3、 Frequently Asked Questions (FAQ)

1. Q: Will this product decompose under acidic environment?

A: Yes, it hydrolyzes in acid to furfural and ethanol.

2. Q: Can it be directly used as final fragrance?

A: No, it is only an intermediate for flavor synthesis.

3. Q: What is its main function in multi‑step synthesis?

A: It protects aldehyde group to avoid side‑reactions.

4. Q: Is it hazardous goods for transportation?

A: No, it is general combustible chemical.

5. Q: What shall we keep away from during storage?

A: Keep away from strong acid, oxidants and heat source.

4、 Application Cases

1. Aldehyde‑group protection for furan‑ring modification:

Used to shield reactive aldehyde group, prevent oxidation and polymerization during nitration and other reactions.

2. Substrate for palladium‑catalyzed cross‑coupling reaction:

Prepare 5‑aryl‑2‑furaldehyde intermediates for early‑stage drug screening via C‑C coupling with aryl halides.

3. Synthetic precursor for nutty & roasted‑note flavor compounds:

Synthesize furan‑type flavor molecules; better stability than free furfural under alkaline formula system.

4. Lab substrate for bio‑based chemical process research:

Conduct acetal‑exchange reaction to develop potential fuel additive candidates and evaluate solid‑acid catalyst performance.

5. Laboratory building‑block for pharmaceutical lead‑compound synthesis:

Protect aldehyde during molecular assembly for furan‑containing lead substances, only for in‑vitro bioactivity test, non‑API.

5、 Safety and Storage

Store in tightly closed container. Keep in cool, dry and well‑ventilated place. Keep away from strong acids, oxidants and heat sources.
