Cyclohexanecarboxylic Acid CAS 98-89-5 Sourcing Guide
A qualified Cyclohexanecarboxylic Acid CAS 98-89-5 request should define the exact identity, intended technical context, buyer specification, analytical methods, quantity, documents and destination before price or sample comparison. The old webpage’s application list and supplier claims are not enough to establish current purity, grade, inventory, regulatory status or suitability.
Use the right page for the right intent
| Page | Primary intent | What it should answer |
|---|---|---|
| This sourcing guide | Specification and supplier qualification | What to define, request and verify before procurement |
| Structure and identity guide | Names, structure and reference properties | CAS, formula, identifiers, synonyms, structure and public-source boundaries |
| Product page | Current commercial handoff | Specification, methods, lot COA, SDS, sample, packaging, MOQ and lead time request |
Identity fields to place on the RFQ
NIST, PubChem and FDA GSRS align on the parent substance. Put more than the common name on the procurement record so a substituted acid, salt, ester, acid chloride or aldehyde is not selected by mistake.
| Name | Cyclohexanecarboxylic acid |
|---|---|

Specification and method checklist
| Qualification item | What to define or request | Why it matters |
|---|---|---|
| Identity | Accepted names, CAS, structure, identity methods and reference standard | Prevents confusion with related cyclohexane derivatives |
| Assay | Required limit, method, units, calculation basis and applicable lot result | A public formula or old “99%” field is not a current assay |
| Appearance / phase | Controlled description, test temperature, method and acceptance criteria | The material may be near a phase transition at ambient conditions |
| Related substances | Named impurities, methods, reporting thresholds and limits | “Purity” alone does not define the impurity profile |
| Benzoic acid | Whether it is a required controlled impurity, with method, units and limit | The historical page listed it without a current specification reference |
| Water / moisture | Named method, units, limit and applicable lot result | The old page omitted a clear unit and method |
| Residual solvents and other controls | Buyer-required analytes, methods, limits and destination-market basis | Requirements depend on process and product context |
| Documents | Current supplier specification, applicable lot COA, current SDS and requested declarations | Confirms which claims apply to the offered lot |
How to qualify an application claim
Chemical identity does not prove performance in a pharmaceutical, polymer, coating, rubber, flavour, fragrance, cleaning or agricultural system. Before a use statement appears in a specification or quotation, connect it to the exact downstream material or process and define the evidence required by the buyer.
| Proposed context | Minimum information to provide | Boundary |
|---|---|---|
| Chemical synthesis or intermediate | Named transformation, target molecule, process constraints and impurity sensitivity | Starting-material identity does not establish downstream efficacy |
| Polymer, coating, rubber or additive | Formulation, performance target, processing conditions and validation method | Do not infer compatibility or performance from a generic application list |
| Flavour context | Use level, specification, destination market, applicable positive list and buyer regulatory review | WHO/JECFA No. 961 is a scoped flavour evaluation, not universal food approval |
| Research use | Protocol, identity/purity need, analytical method and acceptance criteria | A literature mention is not proof of a commercial grade or intended use |
| Regulated finished product | Quality standard, filing pathway, destination market and competent review | A CAS record or website category does not establish authorization |
WHO/JECFA flavour boundary
The WHO/JECFA Cyclohexanecarboxylic Acid record identifies JECFA No. 961 and FEMA No. 3531 and reports a 2002 conclusion of no safety concern at then-current intake levels when used as a flavouring agent. This supports a narrow regulatory-source statement. It does not establish that a current Longchang lot meets a flavour specification or is permitted at any use level in every destination market.
Historical webpage fields requiring confirmation
The earlier product record showed 99%, appearance, benzoic acid, moisture, packaging and one-time “Results” values without a visible current controlled specification number, method set, lot identity, effective date or approval status. Treat them as RFQ questions only. The old anti-pregnancy and schistosomiasis-drug wording is removed because a raw-material page must not give medical-use or treatment claims.
- Ask whether the historical 99.0% minimum is still applicable and request the method and current specification.
- Do not reuse 99.58%, 0.15% or 0.2 as current lot results without an identified applicable lot COA.
- Ask whether 25 kg or 200 kg packaging is currently offered for the requested destination and quantity.
- Request current inventory, MOQ, quotation validity and confirmed lead time instead of assuming availability.
Safety and SDS boundary
This sourcing guide is not an SDS and does not provide site-specific handling or first-aid instructions. Request the current supplier SDS and use it with the buyer’s process, local rules and workplace risk assessment to define classification, receipt, storage, transfer, processing, transport and disposal controls.
Supplier and commercial qualification
- State sample quantity, full quantity, destination and requested delivery window.
- Define packaging constraints and any material-contact requirements.
- List required documents, questionnaires and declarations.
- Request current MOQ, availability, quotation validity and destination-specific lead time.
- Complete analytical, quality, regulatory and process review before approval or use.
