Ethyl 1-ethyl-4-(4-fluorophenoxy)-3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate CAS 1092344-19-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 1-ethyl-4-(4-fluorophenoxy)-3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate.

CATO supplies Ethyl 1-ethyl-4-(4-fluorophenoxy)-3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate (CAS 1092344-19-8), a certified reference material (molecular formula C18H18FN3O3, MW 343.35 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl 1-ethyl-4-(4-fluorophenoxy)-3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 343.35 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), Ethyl 1-ethyl-4-(4-fluorophenoxy)-3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate 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.
