(E)-2-((4-chlorophenyl)thio)-1-(6-methylthiazolo[3,2-b][1,2,4]triazol-5-yl)ethan-1-one O-isopropyl oxime CAS 866131-17-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-2-((4-chlorophenyl)thio)-1-(6-methylthiazolo[3,2-b][1,2,4]triazol-5-yl)ethan-1-one O-isopropyl oxime.

CATO supplies (E)-2-((4-chlorophenyl)thio)-1-(6-methylthiazolo[3,2-b][1,2,4]triazol-5-yl)ethan-1-one O-isopropyl oxime (CAS 866131-17-1), a certified reference material (molecular formula C16H17ClN4OS2, MW 380.92 g/mol) for analytical method development and quality control.

Structurally, (E)-2-((4-chlorophenyl)thio)-1-(6-methylthiazolo[3,2-b][1,2,4]triazol-5-yl)ethan-1-one O-isopropyl oxime (C16H17ClN4OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 380.92 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
