3,5-Di-p-tolyl-4,5-dihydroisoxazole CAS 20821-96-9

Description

Compared with other compounds in its class, the molecular weight of 251.32 g/mol gives 3,5-Di-p-tolyl-4,5-dihydroisoxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3,5-Di-p-tolyl-4,5-dihydroisoxazole (CAS 20821-96-9), a certified reference material (molecular formula C17H17NO, MW 251.32 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3,5-Di-p-tolyl-4,5-dihydroisoxazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 251.32 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 3,5-Di-p-tolyl-4,5-dihydroisoxazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
