2-Acetylfuran | CAS 1192-62-7

A furan methyl ketone with documented cefuroxime-related precursor context and separate aroma-grade applications, making chemical identity, related-furan control and the distinction between synthesis and flavour requirements central to sourcing.

Product overview

2-Acetylfuran carries a methyl ketone at the 2-position of a furan ring. The same structure is named 2-furyl methyl ketone or 1-(furan-2-yl)ethanone, and differs from the aldehyde furfural. Its applications include a role in cefuroxime production and use as an aroma ingredient. These uses lead to different purchasing criteria. Synthesis work focuses on identity, assay and reaction-relevant furan impurities; aroma applications additionally involve sensory assessment and intended-use documentation. State the application and required grade when requesting a sample or quotation.

Application context

For pharmaceutical synthesis, 2-acetylfuran is associated with cefuroxime production and supplies a furan-ketone starting structure. The receiving process determines the required assay and the related compounds to monitor. In aroma applications, qualification also considers organoleptic properties and documentation for the intended use. Buyers should specify whether evaluation is for a synthetic precursor or an aroma ingredient, then request the corresponding analytical and sensory information. Any origin requirement should be stated separately and supported by documentation for the selected material.

Chemistry and synthetic role

The carbonyl is part of an acetyl group attached to the furan ring. It is a methyl ketone rather than an aldehyde, so neither furfural nor a differently positioned acetylfuran is an identity-equivalent substitute.

Quality review

Confirm the 2-furyl methyl ketone identity

Use spectral or chromatographic identity evidence that distinguishes the ketone from furan aldehydes and positional alternatives.

Define related-furan controls

Agree an assay and suitable GC profile. Include specific furan impurities only when the process history or application identifies them as relevant.

Separate chemical and aroma qualification

For aroma use, agree sensory acceptance criteria, the required grade and the origin documentation needed for the intended application.

Preparing a specification

State 2-acetylfuran, CAS 1192-62-7, and whether the enquiry concerns synthesis or a qualified aroma application. Specify identity, assay, related-furan criteria and, where relevant, sensory and intended-use documentation without assuming a universal grade.

Packaging and storage

Packaging format, closure and net weight should be agreed for the selected grade, order quantity and destination. Request the actual supplier SDS and confirm its storage and transport instructions before receipt.

Documentation

Request COA, SDS and the analytical specification. For aroma applications, state the required intended-use and origin documents and confirm their availability for the proposed grade.

Procurement questions

Is this furfural?

No. 2-Acetylfuran is a methyl ketone, whereas furfural is an aldehyde.

Can synthesis grade be treated as flavour grade?

Not solely from the CAS or assay. Qualification and supporting documentation must match the intended use.

Which documents matter when origin is a purchasing requirement?

State the required origin designation and confirm the supporting manufacturer and process documentation for the proposed grade.
