Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 123.11 g/mol gives 3-Amino-5-methylisoxazole-4-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Amino-5-methylisoxazole-4-carbonitrile (CAS 41808-52-0), a certified reference material (molecular formula C5H5N3O, MW 123.11 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, 3-Amino-5-methylisoxazole-4-carbonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 123.11 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), 3-Amino-5-methylisoxazole-4-carbonitrile 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.
