Which specification points matter when purchasing 6-Methyl-4-oxoheptanal for synthesis?

Confirm identity against 6-Methyl-4-oxoheptanal, chromatographic assay, related carbonyl compounds, water, color or appearance, residual solvents, storage temperature and any stabilizer declaration. Because the molecule contains both aldehyde and ketone functions, qualify the actual batch in the downstream reaction and follow the current supplier SDS for handling.

6-Methyl-4-oxoheptanal CAS 66471-61-2

6-Methyl-4-oxoheptanal , CAS 66471-61-2 , is a keto-aldehyde intermediate with molecular formula C8H14O2 and molecular weight 142.20 g/mol. It contains both aldehyde and ketone functionality and is offered for research, route development and project synthesis. Unsupported statements that its CAS is unreported, or generic estimates for appearance, density, boiling point and solubility, should not be treated as specifications. Buyers should qualify identity, assay, water, oxidation or condensation by-products, physical form and storage behavior for the exact grade.

CAS: 66471-61-2
Synonyms: 6-Methyl-4-oxoheptanal, 4-Oxo-6-methylheptanal, 6-Methyl-4-oxo-heptanal
Molecular Formula: C₈H₁₄O₂

Identity and physicochemical profile

Item	Technical guidance
Product identity	6-Methyl-4-oxoheptanal
CAS number	66471-61-2
Formula / molecular weight	C₈H₁₄O₂ / 142.20 g/mol
Functional groups	One aldehyde and one ketone group in a branched aliphatic chain
Commercial status	Research or project intermediate with supplier-specific assay, physical form and impurity limits
Key controls	Identity, chromatographic assay, water, oxidation or condensation products, physical form and storage history

Applications and grade selection

6-Methyl-4-oxoheptanal is evaluated as a bifunctional building block in controlled research and fine-chemical route-development projects. Its aldehyde and ketone groups provide two reactive carbonyl sites, but route suitability and impurity formation must be established experimentally for the intended synthesis.

Define the required identity and chromatographic methods plus route-critical impurity limits.
Run a small-scale process comparison covering conversion, selectivity, work-up and final-product quality.
Confirm sample size, physical form, package, temperature and delivery timing before ordering.

Storage and handling

Keep the supplied container tightly closed under the temperature, light and atmosphere conditions stated in the current documentation. Minimize unnecessary air exposure and follow the exact instructions for sampling, equilibration and use.

Safety, documentation and procurement

Handle as a reactive research intermediate using suitable gloves, eye protection and ventilation according to the current SDS and site assessment. A quotation should state the reaction, specification, quantity, packaging, destination and documentation needs.
