CAS and stereochemical qualification
NIST lists CAS 2437-95-8 for alpha-pinene and identifies its stereoisomers. PubChem CID 6654 and the FDA food-substance inventory use CAS 80-56-8 for generic alpha-pinene, while PubChem includes 2437-95-8 among its synonyms. A name or formula alone does not define optical composition, assay, related terpenes or market suitability.
Include the required CAS basis, optical rotation or enantiomeric range where relevant, assay method and related-terpene limits in the RFQ. Confirm that the CAS shown on the current supplier specification, COA and SDS matches the buyer’s requirement.
Legacy source-record fields requiring confirmation
The values below come from the historical Longchang entry. They are qualification prompts—not a current specification, batch result or storage guarantee.
| Field | Historical source-record value | RFQ action |
|---|---|---|
| Appearance | Colorless transparent liquid | Confirm current method and acceptable color/appearance range |
| Boiling point | 155–156 °C | Confirm pressure basis, method and current limit |
| Density | 0.858 g/mL at 25 °C | Confirm temperature, method and range |
| Refractive index | n20/D 1.465 | Confirm temperature, method and range |
| Storage field | 0–6 °C | Request the current SDS and supplier storage/transport statement |
| Historical melting-point row | Internally inconsistent label/value | Excluded from this page until a current method and limit are supplied |
Information to include in an Alpha-Pinene RFQ
- CAS basis and required stereochemical or optical-rotation range.
- Assay method and limits for beta-pinene and other related terpenes.
- Water, color, density, refractive index and process-specific limits.
- Quantity, packaging constraints, destination country and delivery requirements.
- Current supplier specification, applicable lot COA, current SDS status and required market documents.
Application and regulatory boundary
Alpha-pinene identity records include solvent and fragrance/flavor-related contexts. The FDA inventory lists alpha-pinene under CAS 80-56-8 as a flavoring agent or adjuvant and cites specific regulations. That does not prove this CAS 2437-95-8 source record is food grade, universally approved or suitable for a buyer’s finished product. Application suitability must be evaluated against the current specification, lot documents, intended process and destination-market rules.
Regulatory reference: FDA Substances Added to Food: Alpha-Pinene.
Safety and handling boundary
Use the current supplier SDS and the buyer’s site procedures to assess flammability, exposure controls, incompatibilities, storage, transport and disposal. This sourcing page is not a substitute for an SDS, risk assessment or finished-product safety review.
