Overview

[3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro[4.5]dec-3-en-4-yl] 2,2-dimethylbutanoate (CAS 148477-71-8) is a spirocyclic organic compound with significant biological activity and regulatory classification concerns. This complex organochlorine compound features a distinctive spirocyclic structure combining a lactone ring system with a dichlorophenyl substituent and a dimethylbutanoate ester group. With a molecular formula of C21H24Cl2O4 and molecular weight of 411.3 g/mol, this substance represents an advanced synthetic intermediate in pharmaceutical and agrochemical applications. The presence of two chlorine atoms on the phenyl ring contributes to its enhanced stability and biological activity profile. The compound carries significant safety classifications under the CLP Regulation, including Category 1B carcinogenicity, Category 2 reproductive toxicity, and Category 2 specific target organ toxicity following repeated exposure. Additional hazards include skin sensitization potential and chronic aquatic toxicity. These classifications necessitate stringent handling protocols, specialized storage conditions, and comprehensive risk assessment procedures. The GHS08, GHS07, and GHS09 pictograms reflect its serious health hazards and environmental concerns. Transportation falls under ADR Class 9 (miscellaneous dangerous substances). Industrial applications typically include use as a synthetic intermediate in pharmaceutical manufacturing, particularly in the development of bioactive compounds. The spirocyclic framework makes it valuable in medicinal chemistry for creating novel drug candidates with improved pharmacokinetic properties. Its structural complexity also finds application in specialized agrochemical formulations. Unlike simpler aromatic compounds such as 4-[(4-amino-3-chlorophenyl)methyl]-2-chloroaniline, this spirocyclic derivative offers unique three-dimensional molecular architecture essential for specific biological targets. OYSI maintains strategic inventory of this specialized compound to support European pharmaceutical and chemical manufacturing sectors, ensuring reliable supply for qualified industrial applications.
