Description
CATO manufactures 7’-Bromospiro[cyclopropane-1,3’-indolin]-2’-one 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.
7’-Bromospiro[cyclopropane-1,3’-indolin]-2’-one (CAS 1360935-49-4) is a high-purity analytical reference standard with the molecular formula C10H8BrNO and a molecular weight of 238.08 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 7’-Bromospiro[cyclopropane-1,3’-indolin]-2’-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
