1-(3-Chloro-4-methylphenyl)-4-(1-methyl-1H-benzo[d]imidazol-2-yl)pyrrolidin-2-one CAS 847397-33-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-Chloro-4-methylphenyl)-4-(1-methyl-1H-benzo[d]imidazol-2-yl)pyrrolidin-2-one.

1-(3-Chloro-4-methylphenyl)-4-(1-methyl-1H-benzo[d]imidazol-2-yl)pyrrolidin-2-one (CAS 847397-33-5), molecular formula C19H18ClN3O and molecular weight 339.82 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(3-Chloro-4-methylphenyl)-4-(1-methyl-1H-benzo[d]imidazol-2-yl)pyrrolidin-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.82 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-(3-Chloro-4-methylphenyl)-4-(1-methyl-1H-benzo[d]imidazol-2-yl)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.
