Is 4-Oxopentanal adequately identified by the formula C5H8O2?

No. The formula does not distinguish 4-Oxopentanal from other C5H8O2 structures. This material is the ketoaldehyde CH3COCH2CH2CHO, with aldehyde and ketone functions at defined positions. Confirm the name, CAS 626-96-0 and an agreed chromatographic or spectral identity method rather than matching formula alone.

4-Oxopentanal CAS 626-96-0

4-Oxopentanal (CAS 626-96-0), also called Levulinaldehyde or 4-Ketopentanal, is a keto aldehyde used in controlled carbonyl chemistry, cyclization and specialty-intermediate synthesis. Confirm identity, chromatographic assay, water, oxidation products, condensation products and physical form against the current COA and SDS.

Applications and grade selection

4-Oxopentanal may be evaluated in controlled carbonyl chemistry, cyclization, reductive transformation and specialty-intermediate synthesis. Its aldehyde and ketone functions can support selectivity but also create storage and reaction complexity.

Agree the identity technique, assay method and limits for oxidation, condensation and route-derived impurities.
Confirm the delivered physical form, sampling method, storage temperature and retest conditions.
Run the intended reaction at small scale and compare conversion, selectivity and downstream impurity carryover.

Storage and handling

Keep the material tightly sealed under the temperature, light and atmosphere conditions stated in the current documentation. Minimize opening and promptly record any color, phase or chromatographic change during qualification.

Safety, documentation and procurement

Handle as a reactive carbonyl intermediate using suitable gloves, eye protection and ventilation under the current SDS and site assessment. Procurement should define test methods, stability needs, quantity, packaging, destination and documentation.
