1-(4-Amino-2-chlorophenyl)pyrrolidin-2-one CAS 444002-88-4

Description

The occurrence of 1-(4-Amino-2-chlorophenyl)pyrrolidin-2-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4-Amino-2-chlorophenyl)pyrrolidin-2-one (CAS 444002-88-4), molecular formula C10H11ClN2O and molecular weight 210.66 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, 1-(4-Amino-2-chlorophenyl)pyrrolidin-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.66 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.

As a certified reference material (CRM), 1-(4-Amino-2-chlorophenyl)pyrrolidin-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.
