Chemical Structure

Ethyl-5-(tributylstannyl)isoxazole-3-carboxylate CAS 126085-91-4 chemical structure

Description

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

CATO supplies Ethyl-5-(tributylstannyl)isoxazole-3-carboxylate (CAS 126085-91-4), a certified reference material (molecular formula C18H33NO3Sn, MW 430.17 g/mol) for analytical method development and quality control.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl-5-(tributylstannyl)isoxazole-3-carboxylate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 430.17 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).

As a certified reference material (CRM), Ethyl-5-(tributylstannyl)isoxazole-3-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.
