(3Z)-3-{[4-(2-chloroacetyl)-1H-pyrrol-2-yl]methylidene}-2,3-dihydro-1H-indol-2-one CAS 866038-33-7 chemical structure

Description

As a certified reference material (CRM), (3Z)-3-{[4-(2-chloroacetyl)-1H-pyrrol-2-yl]methylidene}-2,3-dihydro-1H-indol-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(3Z)-3-{[4-(2-chloroacetyl)-1H-pyrrol-2-yl]methylidene}-2,3-dihydro-1H-indol-2-one (CAS 866038-33-7), molecular formula C15H11ClN2O2 and molecular weight 286.71 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (3Z)-3-{[4-(2-chloroacetyl)-1H-pyrrol-2-yl]methylidene}-2,3-dihydro-1H-indol-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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