Name and structure qualification
Cyclohexanal, Cyclohexanecarbaldehyde and Cyclohexanecarboxaldehyde are supported names for CAS 2043-61-0. Confirm the CAS and structure rather than relying only on formula C7H12O or partial search phrases. The substance is an aliphatic aldehyde, not benzaldehyde, cyclohexanone or an unsaturated cyclohexene carboxaldehyde.
Legacy source-record fields requiring confirmation
The values below are historical Longchang fields. They are qualification prompts—not a current specification, lot result, grade, packaging commitment, inventory statement or delivery guarantee.
| Field | Historical source-record value | RFQ action |
|---|---|---|
| Udseende | Væske | Confirm current color/clarity description, method and range |
| Renhed | ≥99% | Confirm current limit, analytical method, basis and applicable lot COA |
| Fugt | ≤0.1% | Confirm current limit, test method, units/basis and lot result |
| Use statements | Organic synthesis, reductive amination and Horner–Emmons context | Validate the exact reaction, impurity profile, scale and market |
| Emballage | 200 L/drum | Confirm current net amount, material/lining, closure, headspace and transport status |
| Delivery | Within 5–7 working days | Confirm current availability and lead time for the destination and quotation date |
| Opbevaring | Cool, dry and away from direct sunlight | Use the current supplier SDS to confirm temperature, atmosphere and site controls |
Information to include in a CAS 2043-61-0 RFQ
- Product name, CAS 2043-61-0 and structure identifier where needed.
- Assay method/basis, appearance, water or moisture method and route-specific physical-property limits.
- Named related substances, unknown impurity limits, total impurities and any oxidation/stability markers.
- Intended transformation, quantity, scale, packaging/headspace constraints, destination and transport requirements.
- Current supplier specification, applicable lot COA, current SDS status, document versions, availability and quotation validity.
Application boundary
CAS 2043-61-0 may be evaluated as an aldehyde building block or intermediate in a qualified synthetic route. Identity alone does not establish API, pharmaceutical, food, flavor, fragrance, polymer, coating, adhesive, cosmetic, agrochemical or finished-product suitability. The buyer must validate the material against the reaction, impurity profile, scale, process controls and destination-market requirements.
Safety and handling boundary
A current third-party SDS classifies its referenced material as a category-3 flammable liquid and a category-2 skin/eye irritant. Use the current supplier SDS and site-specific procedures to establish the classification, receipt, storage, transfer, reaction, transport and disposal controls for the material supplied. This sourcing page is not a substitute for an SDS or process risk assessment.
