Name and structure qualification
The systematic name specifies an acyl chloride connected to a cyclopentyl group through a propanoyl chain. Do not substitute cyclopentyl chloride, cyclopropyl chloride, cyclopropyl carbonyl chloride or cyclopentanecarbonyl chloride by partial-name similarity. Include the CAS and structure identifier in the RFQ when ambiguity would affect the route.
Legacy source-record fields requiring confirmation
The values below are historical Longchang fields. They are qualification prompts—not a current specification, lot result, grade, application approval, packaging commitment or availability statement.
| Field | Historical source-record value | RFQ action |
|---|---|---|
| Appearance | Light yellow liquid | Confirm current method and color/appearance range |
| Assay | 98%; historical result 98.20% | Confirm current limit, method, basis and applicable lot COA |
| 3-Cyclopentylpropionic acid | Historical result 0.6%; no limit shown | Confirm analyte name, method and maximum limit |
| Other substances | Historical result 1.2%; no identities or limit shown | Define named impurities, unknowns, total impurities and method |
| Use field | “API and electronic use” | Not treated as validated suitability; state the exact process and market |
| Packaging | 50 kg steel drum | Confirm current size, lining, closure, moisture protection and transport status |

Application boundary
CAS 104-97-2 is an acyl chloride that may be evaluated as an intermediate in a qualified synthetic route. Chemical identity alone does not establish API, electronic, pharmaceutical, fragrance, 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
Use the current supplier SDS and site-specific procedures to assess corrosivity, moisture/reactivity controls, exposure prevention, storage, transport, reaction/quench design and disposal. This sourcing page is not a substitute for an SDS or process risk assessment.
