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
Erscheinungsbild Hellgelbe Flüssigkeit 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
Andere Stoffe 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
Verpackung 50 kg steel drum Confirm current size, lining, closure, moisture protection and transport status

Information to include in a CAS 104-97-2 RFQ

  • Product name, CAS 104-97-2 and structure identifier where needed.
  • Assay method/basis, appearance, water and route-specific limits.
  • Limits for 3-cyclopentylpropionic acid, named related substances, unknowns and total impurities.
  • Intended transformation, quantity, packaging/lining constraints, destination and delivery requirements.
  • Current supplier specification, applicable lot COA, current SDS status and required market/transport documents.

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.
