Heptanal is a linear aliphatic aldehyde used as a chemical raw material in industrial formulation processes. This compound, also known in industry as n-heptanal, heptaldehyde, or enanthaldehyde, contains a reactive aldehyde functional group that readily participates in oxidation, condensation, and acetal formation reactions. Identified by CAS 111-71-7, it is typically applied as a flavor and fragrance intermediate, where controlled reactivity and carbon chain length are required for downstream synthesis and formulation stability.
In industrial supply contexts, this product is available with competitive factory pricing, customized specifications, complete documentation including MSDS, TDS, COA, and supports bulk supply for manufacturing use.

Application Areas
(1) Spices and essence industry
It is used for blending citrus, rose, jasmine, fruit and other flavor essence.
As a food additive (complying with food safety standards), it is used to enhance the flavor of cream, cheese, nuts, and other foods.
(2) Organic synthesis
Used for synthesizing compounds such as heptanol, heptanoic acid, unsaturated aldehydes, etc.
As a pharmaceutical intermediate (such as certain antibiotics, antifungal drugs).
Used for the synthesis of surfactants and plastic plasticizers.
(3) Other applications
A small amount is used in industries such as rubber, coatings, lubricants, etc.
Storage conditions
(1) Environmental conditions
Temperature: Store in a cool, ventilated place, recommended to refrigerate at 2-8 ° C (to slow down oxidation).
Avoid light: Use brown glass bottles or opaque containers to prevent light from decomposing.
Sealing: Strictly isolate air (can be filled with nitrogen for protection) to prevent oxidation into heptanoic acid.
(2) Container selection
Recommended materials: Glass, stainless steel, or polyethylene (HDPE) containers.
Avoid using metal containers such as copper and aluminum that are prone to corrosion.
(3) Isolation storage
Stay away from oxidants (such as peroxides, nitrates), strong acids, and strong bases.
Safety precautions
(1) Personal protection
Respiratory protection: Use organic vapor masks (such as 3M 6001) in poorly ventilated areas.
Skin protection: Wear nitrile/chloroprene rubber gloves and chemical resistant clothing.
(2) Fire and explosion prevention
Flash point: 38 ° C (closed cup), classified as flammable liquid
Equipped with dry powder fire extinguishers (Class ABC) or carbon dioxide fire extinguishers, do not spray directly with water.
(3) Emergency measures
Inhalation: Move to fresh air. If breathing is difficult, seek medical attention immediately.
Skin contact: Immediately rinse with soapy water and plenty of water for 15 minutes.
Eye contact: Rinse with physiological saline or clean water for at least 15 minutes and seek medical attention.
Ingestion: Do not induce vomiting, rinse your mouth immediately and seek medical attention.
FAQ - Technical & Supply Chain
-
Q:
Are heptanal and heptaldehyde the same substance?
A: Yes. Heptanal and heptaldehyde are common names referring to the same chemical substance and correspond to a single CAS registry entry. -
Q:
Is heptanal intended for industrial formulation rather than laboratory research use?
A: Heptanal is commonly supplied for industrial formulation and synthesis processes, where it functions as a reactive aldehyde intermediate rather than a research-only reagent.
