3-Chloro-5-[(4-methoxyphenethyl)amino]-4-isothiazolecarbonitrile CAS 866009-34-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-5-[(4-methoxyphenethyl)amino]-4-isothiazolecarbonitrile.

CATO supplies 3-Chloro-5-[(4-methoxyphenethyl)amino]-4-isothiazolecarbonitrile (CAS 866009-34-9), a certified reference material (molecular formula C13H12ClN3OS, MW 293.77 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-5-[(4-methoxyphenethyl)amino]-4-isothiazolecarbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.77 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
