Pharmaceutical intermediate
Serves as a building block in the synthesis of active pharmaceutical ingredients and candidate molecules. Its hindered quaternary carbon centre is valued where a conformationally constrained aryl-cyclopentane motif is required.
Organic synthesis building block
The carboxylic acid functions as a versatile handle for amidation, esterification and acyl chloride formation. This makes the compound a convenient C11-C12 scaffold for multi-step fine-chemical routes.
Research and development reagent
Used in medicinal-chemistry and methodology research where a 4-chlorophenyl substituent and a spirocyclic-style cyclopentane framework are needed. The 98% assay supports reproducible laboratory-scale work.
Reference and characterisation material
Suitable as a characterised intermediate for analytical method development and structure-activity studies, identified by MDL number MFCD00001373 and PubChem substance ID 24848501.

What is the CAS number and molecular formula of 1-(4-Chlorophenyl)-1-cyclopentanecarboxylic acid?
+
Its CAS number is 80789-69-1 and its molecular formula is C12H13ClO2 (linear formula ClC6H4C5H8CO2H). The molecular weight is 224.68 g/mol, the EC number is 279-552-1 and the MDL number is MFCD00001373.
What grade and purity does Tech Serve Solutions supply?
+
Tech Serve Solutions supplies this compound at a typical assay of 98% as a research and synthesis grade material. We do not represent it as a USP, BP or EP pharmacopoeia grade; a certificate of analysis is provided with each batch and full specifications are available on request.
What are the safety and handling requirements?
+
Handle the material with eye protection, gloves and, where airborne dust is possible, an N95 (US) or P1 (EN 143) respirator filter. It is classified WGK 3 in Germany, indicating a severe hazard to water, so it must be kept out of drains, soil and watercourses. Always consult the current Safety Data Sheet before use.
How is 1-(4-Chlorophenyl)-1-cyclopentanecarboxylic acid packed, shipped and exported?
+
It is packed as a solid in sealed, clearly labelled containers sized to the order, from research quantities to bulk. Tech Serve Solutions exports worldwide with full documentation, including the certificate of analysis and Safety Data Sheet, and packaging that protects the product against moisture and contamination in transit.
How do I request a sample or quote?
