Chemical Structure

3-Methyl-5-(1H-pyrrol-2-yl)isoxazole CAS 94405-06-8 chemical structure

Description

As a certified reference material (CRM), 3-Methyl-5-(1H-pyrrol-2-yl)isoxazole 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.

3-Methyl-5-(1H-pyrrol-2-yl)isoxazole (CAS 94405-06-8), molecular formula C8H8N2O and molecular weight 148.16 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, 3-Methyl-5-(1H-pyrrol-2-yl)isoxazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.16 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.
