Are Heptanal and Heptaldehyde the same substance?

Yes. Heptanal, Heptaldehyde, 1-Heptanal, Enanthaldehyde and Oenanthaldehyde are names used for CAS 111-71-7 and formula C₇H₁₄O. Confirm the CAS number and linear aldehyde identity because similarly named C7 aldehyde isomers are different materials.

Why should acid value and storage history be checked for Heptanal?

Heptanal can oxidize to the corresponding acid and may undergo other composition changes during storage. Review GC assay, acid value, water, color, odor, stabilizer status, production or retest date and storage history against the intended fragrance, synthesis or formulation requirements.

Which details should a bulk Heptanal inquiry include?

State the required grade and use, GC assay, acid-value limit, water, color, refractive index or density, stabilizer requirement, quantity, packaging and destination. Request the lot COA together with TDS and SDS, and agree the sampling and release methods before shipment.

Heptanal (Heptaldehyde) CAS 111-71-7

Heptanal (Heptaldehyde), CAS 111-71-7, is also known as n-heptanal or enanthaldehyde. It is an aliphatic aldehyde used in fragrance evaluation and organic synthesis. Before technical review, specify the required GC assay, water, acid value, color and stabilizer status for the offered grade.

CAS: 111-71-7
Synonyms: Heptanal, Heptaldehyde, n-Heptanal, Enanthaldehyde, Heptyl aldehyde
Einecs: 203-898-4
Molecular Formula: C₇H₁₄O
Grade: GC assay, water, acid value, color, stabilizer requirement
Package: Confirm compatible sealed packaging, oxidation or static-control needs and dangerous-goods transport conditions.

Applications and Grade Selection

Heptanal (Heptaldehyde) is evaluated for fragrance evaluation and organic synthesis. Grade selection should be based on GC assay, water, acid value, color, stabilizer requirement and application testing, not on a generic purity, grade or performance claim.

Storage and Packaging

Confirm compatible sealed packaging, oxidation or static-control needs and dangerous-goods transport conditions.

Safety and Documentation

Review the current SDS before handling Heptanal (Heptaldehyde). Confirm hazards, PPE, incompatibilities, emergency measures, transport classification and receiving-site controls for the exact supplied form; the product page is not a substitute for lot and shipment documents.
