Chemical Structure

3-(tert-Butyl)-4-(3-(dimethylamino)propyl)-1-ethyl-1,4-dihydroindeno[1,2-c]pyrazol-4-ol CAS 68946-21-4 chemical structure

Description

3-(tert-Butyl)-4-(3-(dimethylamino)propyl)-1-ethyl-1,4-dihydroindeno[1,2-c]pyrazol-4-ol (CAS 68946-21-4) is a high-purity analytical reference standard with the molecular formula C21H31N3O and a molecular weight of 341.49 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3-(tert-Butyl)-4-(3-(dimethylamino)propyl)-1-ethyl-1,4-dihydroindeno[1,2-c]pyrazol-4-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 341.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-(tert-Butyl)-4-(3-(dimethylamino)propyl)-1-ethyl-1,4-dihydroindeno[1,2-c]pyrazol-4-ol 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.
