3-Phenyl-2-(2-thienylcarbonyl)indeno[1,2-c]pyrazol-4(2H)-one CAS 1020251-78-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Phenyl-2-(2-thienylcarbonyl)indeno[1,2-c]pyrazol-4(2H)-one.

3-Phenyl-2-(2-thienylcarbonyl)indeno[1,2-c]pyrazol-4(2H)-one (CAS 1020251-78-8), molecular formula C21H12N2O2S and molecular weight 356.40 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-Phenyl-2-(2-thienylcarbonyl)indeno[1,2-c]pyrazol-4(2H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 3-Phenyl-2-(2-thienylcarbonyl)indeno[1,2-c]pyrazol-4(2H)-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.
