Methyl 6-(1-ethyl-1h-pyrazol-3-yl)-3-methylisoxazolo[5,4-b]pyridine-4-carboxylate CAS 1172804-59-9 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 Methyl 6-(1-ethyl-1h-pyrazol-3-yl)-3-methylisoxazolo[5,4-b]pyridine-4-carboxylate.

CATO supplies Methyl 6-(1-ethyl-1h-pyrazol-3-yl)-3-methylisoxazolo[5,4-b]pyridine-4-carboxylate (CAS 1172804-59-9), a certified reference material (molecular formula C14H14N4O3, MW 286.29 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Methyl 6-(1-ethyl-1h-pyrazol-3-yl)-3-methylisoxazolo[5,4-b]pyridine-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Methyl 6-(1-ethyl-1h-pyrazol-3-yl)-3-methylisoxazolo[5,4-b]pyridine-4-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.
