Cyclohexanecarboxylic Acid: Structure, Identity and Reference Properties

Cyclohexanecarboxylic acid is the monocarboxylic acid formed by attaching a carboxyl group to a cyclohexane ring. NIST, PubChem and the FDA Global Substance Registration System align on CAS 98-89-5, formula C₇H₁₂O₂, molecular weight about 128.17 g/mol and InChIKey NZNMSOFKMUBTKW-UHFFFAOYSA-N. These identity records answer structure and naming questions; they do not establish the specification, appearance, purity, use authorization or suitability of a current Longchang lot.

Cyclohexanecarboxylic acid identity at a glance

Identity references: NIST Chemistry WebBook CAS 98-89-5, PubChem CID 7413 и FDA GSRS UNII H9VKD9VL18. These are public identity sources, not Longchang specifications or lot documents.

What does the structure show?

The structure contains a saturated six-membered cyclohexane ring and one carboxylic-acid group, written as C1CCC(CC1)C(=O)O. The formula can also be written C₆H₁₁CO₂H. The FDA GSRS record identifies the substance as achiral with no defined stereocenters. A search for “structure of cyclohexane carboxylic acid” should therefore resolve to this exact parent acid, not to a substituted acid, an ester, an acid chloride, a salt or Cyclohexanecarboxaldehyde CAS 2043-61-0.

Are Cyclohexanoic Acid and Cyclohexanecarboxylic Acid the same?

Public identity records list Cyclohexanoic acid, Hexahydrobenzoic acid, Carboxycyclohexane, Cyclohexylcarboxylic acid и Cyclohexylmethanoic acid as names associated with the CAS 98-89-5 parent substance. A procurement record should still use the preferred name, CAS number and structural identifier together so that a similar substituted derivative is not selected by name alone.

Reference properties versus a current supplier specification

NIST provides evaluated identity, thermochemistry, phase-change and spectral records. PubChem aggregates computed and experimental property contributions. Those data are useful for literature screening, but a value copied from a public database is not a current Longchang specification or lot result.

What does the WHO/JECFA flavour record establish?

Сайт WHO/JECFA record for Cyclohexanecarboxylic Acid, JECFA No. 961 lists CAS 98-89-5, FEMA No. 3531 and the functional class “Flavouring Agent.” Its 2002 evaluation reports no safety concern at the then-current levels of intake when used as a flavouring agent.

That conclusion is scoped to the evaluated flavour use and exposure context. It is not a declaration that every supplier lot is food grade, approved in every country, suitable at any concentration or compliant with a buyer’s finished product. A food or flavour project still requires the current applicable specification, purity/impurity data, use level, destination-market rules and the buyer’s regulatory assessment.

Frequently asked questions

What is the formula of Cyclohexanecarboxylic Acid?

The molecular formula is C₇H₁₂O₂. NIST reports a molecular weight of 128.1690, commonly rounded to 128.17 g/mol.

What is its structure?

It is a cyclohexane ring bearing one carboxylic-acid group. The canonical SMILES is C1CCC(CC1)C(=O)O.

Is Cyclohexanoic Acid a different CAS?

In the reviewed public records, Cyclohexanoic Acid is a synonym associated with CAS 98-89-5. Confirm the full identity because similar substituted cyclohexane acids are different materials.

Does the JECFA record make every lot food grade?

No. It documents a scoped flavour evaluation. Lot quality, use level, destination-market compliance and finished-product suitability require separate current evidence and buyer approval.
