What is 10-Hydroxydecanoic Acid CAS 1679-53-4?

10-Hydroxydecanoic Acid CAS 1679-53-4 is a saturated C10 omega-hydroxy fatty acid with the formula C10H20O3 and molecular weight about 188.26 g/mol. It contains both a terminal hydroxyl group and a carboxylic acid group.

What other synthesis applications use this omega-hydroxy acid?

It is used in the preparation of macrocyclic musk ingredients and derivatives such as 10-hydroxy-2-decylenic acid, also called queen acid. These applications rely on the long-chain difunctional structure for cyclization or chain extension.

What are the key commercial specifications for 10-Hydroxydecanoic Acid?

Typical commercial material is a white to off-white crystalline powder or flakes with assay at least 98.5% by GC, melting point about 75-78 C, low moisture, and acid value in the high 200s to low 300s mg KOH/g.

What storage and solubility considerations are relevant?

It is soluble in ethanol, methanol, ether, and hot water but only slightly soluble in cold water. Store it sealed in a cool, dry place to limit moisture uptake and preserve crystalline quality.

Product Description

10-Hydroxydecanoic Acid, CAS 1679-53-4, is a saturated C10 omega-hydroxy fatty acid.

Synonyms: 10-Hydroxycapric acid; Omega-hydroxydecanoic acid; 10-Hydroxy decanoic acid; Decanoic acid 10-hydroxy-.

CAS: 1679-53-4.

It has a molecular weight of about 188.26 g/mol and contains both a terminal hydroxyl group and a carboxylic acid group.

It is a white to off-white crystalline powder or flakes with a GC assay of not less than 98.5%.

It has a melting point of about 75–78 °C and an acid value of about 290–305 mg KOH/g.

It is soluble in ethanol, methanol, ether and hot water, and only slightly soluble in cold water.

It is an important bifunctional intermediate used to construct active pharmaceutical ingredients, including idebenone-related compounds.

The terminal alcohol and acid groups allow controlled esterification, oxidation and coupling reactions.

It is used in the preparation of macrocyclic musk ingredients and derivatives such as 10-hydroxy-2-decylenic acid.

It is used in specialized polyesters and plastics where hydroxy-acid monomers modify polymer properties.

It is used as a surfactant intermediate or skin-conditioning agent precursor in advanced cosmetic formulations.

The long-chain difunctional structure supports cyclization and chain extension.

Confirm appearance, GC assay, melting point, moisture, ash, heavy metals, solubility, acid value and packaging.

Store below 30 °C in a cool, dry, well-ventilated place, away from humidity and direct sunlight.

Keep the container tightly closed and sealed to limit moisture uptake and preserve crystalline quality.

Confirm packaging with the requested quantity and destination requirements.
