1-(1,1,3,3,6-Pentamethyl-7-nitro-2,3-dihydro-1H-inden-5-yl)-1H-pyrrole CAS 657405-94-2

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-(1,1,3,3,6-Pentamethyl-7-nitro-2,3-dihydro-1H-inden-5-yl)-1H-pyrrole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.38 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).

1-(1,1,3,3,6-Pentamethyl-7-nitro-2,3-dihydro-1H-inden-5-yl)-1H-pyrrole (CAS 657405-94-2), molecular formula C18H22N2O2 and molecular weight 298.38 g/mol, is a CATO reference standard with documented purity and traceability.

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