Heptaldehyde

What Heptaldehyde Does & Buyer Problems It Solves

What It Does:

• Acts as a key fragrance and flavour building block – heptaldehyde is a direct ingredient in perfumery (contributing fatty, green, and fresh notes) and a precursor to important aroma chemicals including jasmine aldehyde (alpha-amyl cinnamaldehyde), coconut aldehyde, and delta-dodecalactone used in fine fragrances.
• Functions as an intermediate for chemical synthesis – through oxidation to heptanoic acid, reduction to heptyl alcohol (1-heptanol), or condensation reactions, heptaldehyde generates a family of commercially important derivatives used across pharmaceuticals, lubricants, flavours, and industrial chemicals.
• Serves as a reactive component in rubber chemicals – heptaldehyde and its derivatives are used in the preparation of vulcanization accelerators for rubber processing, and the compound itself acts as a solvent and processing aid in rubber and plastics manufacturing.

Buyer Problems It Solves:

• If you need a bio-based, non-petroleum-derived C7 aldehyde for fragrance or aroma chemical synthesis – heptaldehyde from castor oil is 100% vegetable-origin, aligning with bio-based sourcing requirements in the fragrance and flavour industry.
• If your fragrance formulation requires a natural-origin aldehyde building block to replace synthetic C7 aldehydes – our product carries a bio-based origin claim and can be verified as derived from castor oil.
• If sourcing heptaldehyde with consistent purity, predictable lot-to-lot quality, and reliable export capability is a challenge – Nova Industries’ established castor derivative manufacturing gives you a dependable single-source supplier.
• If you require FEMA GRAS status recognition for flavour applications – heptanal is recognised as a flavouring agent (FEMA No. 2541/2542) and is used in food flavour formulations in trace quantities.

Manufacturing & Quality Control

Heptaldehyde at Nova Industries is produced through the pyrolysis (thermal cracking) of ricinoleic acid derived from castor oil:

• Ricinoleic Acid Source: Derived from hydrolysis of high-quality castor oil
• Cracking Process: Controlled thermal cracking of ricinoleic acid yields heptaldehyde and undecylenic acid as co-products
• Distillation & Purification: Product isolated and purified by fractional distillation to achieve target GC purity (≥95%)
• Quality Testing: Purity (GC), Appearance, Specific Gravity, Refractive Index, and odour character tested per batch
• Documentation: Batch CoA, MSDS, and export documents provided with every consignment
