3551-75-5 N,N inverted exclamation mark -Bis(3-methylphenyl)ethanediamide N1,N2-Bis(3-methylphenyl)ethanediamide m-Oxalotoluidide CAS 3551-75-5 chemical structure

Description

As a certified reference material (CRM), 3551-75-5 N,N inverted exclamation mark -Bis(3-methylphenyl)ethanediamide N1,N2-Bis(3-methylphenyl)ethanediamide m-Oxalotoluidide 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.

CATO supplies 3551-75-5 N,N inverted exclamation mark -Bis(3-methylphenyl)ethanediamide N1,N2-Bis(3-methylphenyl)ethanediamide m-Oxalotoluidide (CAS 3551-75-5), a certified reference material (molecular formula C16H16N2O2, MW 268.31 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, 3551-75-5 N,N inverted exclamation mark -Bis(3-methylphenyl)ethanediamide N1,N2-Bis(3-methylphenyl)ethanediamide m-Oxalotoluidide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.31 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.
