ACETALDEHYDE- ▸ Chemical intermediate: Feedstock for acetic acid, acetic anhydride, and acetate esters.
- ▸ Organic synthesis: Building block for pentaerythritol and pyridine derivatives.
- ▸ Resins and dyes: Intermediate in resin, dye, and specialty-chemical manufacture.
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.

Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Acetaldehyde (CAS 75-07-0) is a reactive low-boiling aldehyde used predominantly as a chemical intermediate. It is consumed in the synthesis of acetic acid, acetic anhydride, pentaerythritol, pyridine derivatives, and other organic chemicals, and serves as an intermediate for resins, dyes, and specialty chemistry.
Frequently Asked Questions
What is acetaldehyde commonly used for?
Acetaldehyde (CAS 75-07-0) is a reactive low-boiling aldehyde used predominantly as a chemical intermediate. It is consumed in the synthesis of acetic acid, acetic anhydride, pentaerythritol, pyridine derivatives, and acetate esters, and serves as an intermediate for resins, dyes, and specialty chemistry.
Is acetaldehyde the same as acetone?
No. Acetaldehyde (C2H4O) is an aldehyde, while acetone (C3H6O) is a ketone; they have different structures, CAS numbers, and reactivity. Acetaldehyde, for example, gives a positive Tollens' (silver-mirror) test characteristic of aldehydes, whereas acetone does not.
Does acetaldehyde react with Tollens' reagent?
Yes. As an aldehyde, acetaldehyde reduces Tollens' reagent (ammoniacal silver nitrate), producing the silver-mirror result and being oxidized to acetic acid/acetate. This is a standard distinguishing test for aldehydes versus ketones.
How is acetaldehyde shipped under DOT/transport regulations?
Acetaldehyde is assigned UN 1089, a flammable liquid. Because of its low boiling point and flammability it requires compliant flammable-liquid packaging, marking, and documentation; RawSource provides the SDS and compliant shipping paperwork with every order. Consult the SDS for storage and handling.
How is bulk acetaldehyde packaged and priced?
RawSource supplies reagent acetaldehyde to industrial buyers with CoA and SDS per lot, in packaging suited to its flammability, and quotes by order. Submit a bulk RFQ with your target volume for current pricing and lead time.
