Cyclohexanecarboxylic Acid: Structure, Identity and Reference Properties<\/h1>\n

Cyclohexanecarboxylic acid<\/strong> 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 C7<\/sub>H12<\/sub>O2<\/sub>, molecular weight about 128.17 g\/mol and InChIKey NZNMSOFKMUBTKW-UHFFFAOYSA-N<\/code>. 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.<\/p>\n

Identity references: NIST Chemistry WebBook CAS 98-89-5<\/a>, PubChem CID 7413<\/a> og FDA GSRS UNII H9VKD9VL18<\/a>. These are public identity sources, not Longchang specifications or lot documents.<\/p>\n

What does the structure show?<\/h2>\n

The structure contains a saturated six-membered cyclohexane ring and one carboxylic-acid group, written as C1CCC(CC1)C(=O)O<\/code>. The formula can also be written C6<\/sub>H11<\/sub>CO2<\/sub>H. The FDA GSRS record identifies the substance as achiral with no defined stereocenters. A search for \u201cstructure of cyclohexane carboxylic acid\u201d 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.<\/p>\n

Are Cyclohexanoic Acid and Cyclohexanecarboxylic Acid the same?<\/h2>\n

Public identity records list Cyclohexanoic acid<\/strong>, Hexahydrobenzoic acid<\/strong>, Carboxycyclohexane<\/strong>, Cyclohexylcarboxylic acid<\/strong> og Cyclohexylmethanoic acid<\/strong> 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.<\/p>\n

Reference properties versus a current supplier specification<\/h2>\n

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.<\/p>\n

What does the WHO\/JECFA flavour record establish?<\/h2>\n

Den WHO\/JECFA record for Cyclohexanecarboxylic Acid, JECFA No. 961<\/a> lists CAS 98-89-5, FEMA No. 3531 and the functional class \u201cFlavouring Agent.\u201d Its 2002 evaluation reports no safety concern at the then-current levels of intake when used as a flavouring agent.<\/p>\n

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.<\/p>\n
