Chemical Structure

tert-Butyl 7-bromo-4-chloro-1-oxoisoindoline-2-carboxylate CAS 2628351-94-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl 7-bromo-4-chloro-1-oxoisoindoline-2-carboxylate.

tert-Butyl 7-bromo-4-chloro-1-oxoisoindoline-2-carboxylate (CAS 2628351-94-8), molecular formula C13H13BrClNO3 and molecular weight 346.60 g/mol, is a CATO reference standard with documented purity and traceability.

tert-Butyl 7-bromo-4-chloro-1-oxoisoindoline-2-carboxylate (C13H13BrClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures tert-Butyl 7-bromo-4-chloro-1-oxoisoindoline-2-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
