What is Decanoic Acid CAS 334-48-5?

Decanoic Acid CAS 334-48-5, also called capric acid or n-decanoic acid, is a saturated medium-chain fatty acid with the molecular formula C10H20O2 and EINECS number 206-376-4. It is normally a white to pale yellow crystalline solid with a characteristic fatty odor.

What are the main industrial applications of Decanoic Acid?

Decanoic Acid is used mainly as a chemical intermediate for making decanoate esters, synthetic lubricants, greases, metal soaps and surfactants. It also serves as a building block for plasticizers, flavor and fragrance esters, and other specialty organic compounds.

Why is C10 content controlled in Decanoic Acid?

The C10 content is controlled to keep caprylic acid C8 and lauric acid C12 impurities low, which helps produce consistent downstream esters and avoid shifts in physical properties. Fractionated Decanoic Acid with high C10 purity is preferred for stable lubricants, clear cosmetic ingredients and reliable fragrance esters.

What does the acid value or saponification value tell a buyer?

Acid value and saponification value help confirm fatty acid concentration and chain-length consistency. This product typically has an acid value around 321-329 mg KOH/g and saponification value around 322-330 mg KOH/g, with a low iodine value indicating high saturation.

How should technical, cosmetic, and flavour grades be selected?

The grade should be selected by the end use and regulatory requirement. Cosmetic and flavour grades need suitable color, odor, purity and compliance, while technical grade is used where broader industrial specifications are acceptable and the material is not intended for direct food or personal-care contact.

How should Decanoic Acid CAS 334-48-5 be stored and transported?

Decanoic Acid is supplied in epoxy-lined steel drums, IBCs or heated ISO tanks, with heated handling useful because its melting point is near ambient temperature. Store it in a dry, well-ventilated area away from strong oxidizers and keep containers sealed to avoid moisture and contamination.

Product Description

Decanoic Acid CAS 334-48-5, also called capric acid or n-decanoic acid, is a saturated medium-chain fatty acid with the molecular formula C10H20O2.

Synonyms: Capric acid; Decylic acid; n-Capric acid; n-Decanoic acid.

CAS: 334-48-5.

It has the molecular formula C10H20O2 and a molecular weight of 172.26 g/mol.

It is a white to pale yellow crystalline solid with a characteristic fatty odor.

It has a titer or melting point of about 31.0–32.0 °C, near ambient temperature.

It is a chemical intermediate for making decanoate esters, synthetic lubricants, greases, metal soaps and surfactants.

It serves as a building block for plasticizers, flavor and fragrance esters and other specialty organic compounds.

The C10 content is controlled to keep caprylic acid C8 and lauric acid C12 impurities low.

Fractionated Decanoic Acid with high C10 purity is preferred for stable lubricants, clear cosmetic ingredients and reliable fragrance esters.

A typical specification includes acid value of about 321–329 mg KOH/g and saponification value of about 322–330 mg KOH/g.

It has a low iodine value, indicating high saturation.

Technical, cosmetic and flavour grades are selected by end use and regulatory requirement.

Cosmetic and flavour grades need suitable color, odor, purity and compliance, while technical grade is used for broader industrial specifications.

Confirm appearance, C10 content, C8 and C12 limits, acid value, saponification value, iodine value, color and moisture.

Store in a dry, well-ventilated area away from strong oxidizers and keep containers sealed to avoid moisture and contamination.

Confirm packaging with the requested quantity and destination requirements.
