(E)-ETFBO | CAS 59938-06-6

An E-configured ethoxy trifluoromethyl enone used in fluorinated active-ingredient chemistry, with alkene geometry, stabilizer composition and intact-enone assay central to procurement.

CAS59938-06-6
Molecular formulaC6H7F3O2
Molecular weight168.11 g/mol

Product overview

ETFBO combines a trifluoromethyl ketone with a conjugated ethoxy-substituted double bond. The specified E configuration is part of its identity, rather than an optional grade description. It supplies a fluorinated carbon framework that can be elaborated in active-ingredient synthesis. Proposed material should be assessed for the intact enone and any declared stabilizer, with moisture and thermal history considered when reviewing sample condition.

Chemical identity

Chemical name
(E)-4-Ethoxy-1,1,1-trifluorobut-3-en-2-one (ETFBO)

Application context

Industrial technical literature identifies ETFBO as a synthetic building block for fluorinated agrochemical ingredients. Its role is to deliver the CF3-bearing carbonyl architecture as part of a larger molecular assembly. The ethoxy-substituted alkene provides additional functionality for subsequent route development. For procurement, define the required E-form content, related components and stabilizer compatibility around the actual downstream chemistry. Qualification of the resulting active ingredient remains tied to its own structure and formulation.

Chemistry and synthetic role

The sequence CF3–CO–CH=CH–OEt forms a conjugated enone ether; E geometry describes the alkene arrangement. It is not an ethyl ester.

Quality review

E-form identity

Confirm alkene configuration and agree how any geometric-isomer content is reported.

Declared stabilizer

Identify the inhibitor and concentration in the proposed grade; include it in assay interpretation and process evaluation.

Enone condition

Review intact-compound assay, moisture and degradation-related components with sample handling appropriate to the selected grade.

Preparing a specification

Specify (E)-ETFBO by full name and CAS, E-form assay, geometric-isomer limits, stabilizer composition and moisture or degradation criteria.

Packaging and storage

Confirm container compatibility, closure and net weight for the selected grade and destination. Follow the actual supplier SDS and batch label for storage and transport.

Documentation

Request the batch COA, SDS and analytical methods covering the agreed purchasing specification. Confirm which supporting chromatograms and application-specific records are available from the selected manufacturer.

Procurement questions

Is ETFBO an ester?

No. It contains a ketone and an ethoxy-substituted alkene.

Does the E designation matter?

It specifies the double-bond geometry and belongs in the identity and impurity review.

Can stabilizer content be ignored in the RFQ?

Its identity and level should be assessed with the intended downstream reaction.
