Diethyl 2-(((1-(tert-butyl)-3-methyl-1H-pyrazol-5-yl)amino)methylene)malonate CAS 956543-98-9

Description

Diethyl 2-(((1-(tert-butyl)-3-methyl-1H-pyrazol-5-yl)amino)methylene)malonate (CAS 956543-98-9), molecular formula C16H25N3O4 and molecular weight 323.39 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, Diethyl 2-(((1-(tert-butyl)-3-methyl-1H-pyrazol-5-yl)amino)methylene)malonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.39 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), Diethyl 2-(((1-(tert-butyl)-3-methyl-1H-pyrazol-5-yl)amino)methylene)malonate 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.
