Cyclohexanecarboxylic Acid CAS 98-89-5 Sourcing Guide<\/h1>\n

A qualified Cyclohexanecarboxylic Acid CAS 98-89-5<\/strong> 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.<\/p>\n

Use the right page for the right intent<\/h2>\n

Identity fields to place on the RFQ<\/h2>\n

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.<\/p>\n

How to qualify an application claim<\/h2>\n

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.<\/p>\n

\n\n\n\n\n\n\n\n\n\n
Proposed context<\/th>\nMinimum information to provide<\/th>\nBoundary<\/th>\n<\/tr>\n<\/thead>\n
Chemical synthesis or intermediate<\/td>\nNamed transformation, target molecule, process constraints and impurity sensitivity<\/td>\nStarting-material identity does not establish downstream efficacy<\/td>\n<\/tr>\n
Polymer, coating, rubber or additive<\/td>\nFormulation, performance target, processing conditions and validation method<\/td>\nDo not infer compatibility or performance from a generic application list<\/td>\n<\/tr>\n
Flavour context<\/td>\nUse level, specification, destination market, applicable positive list and buyer regulatory review<\/td>\nWHO\/JECFA No. 961 is a scoped flavour evaluation, not universal food approval<\/td>\n<\/tr>\n
Research use<\/td>\nProtocol, identity\/purity need, analytical method and acceptance criteria<\/td>\nA literature mention is not proof of a commercial grade or intended use<\/td>\n<\/tr>\n
Regulated finished product<\/td>\nQuality standard, filing pathway, destination market and competent review<\/td>\nA CAS record or website category does not establish authorization<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n

WHO\/JECFA flavour boundary<\/h2>\n

Die WHO\/JECFA Cyclohexanecarboxylic Acid record<\/a> 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.<\/p>\n

Historical webpage fields requiring confirmation<\/h2>\n

The earlier product record showed 99%, appearance, benzoic acid, moisture, packaging and one-time \u201cResults\u201d 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.<\/p>\n
