(E)-5-(3-Chlorobenzylidene)-2-mercaptothiazol-4(5H)-one CAS 1784763-10-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-5-(3-Chlorobenzylidene)-2-mercaptothiazol-4(5H)-one.

(E)-5-(3-Chlorobenzylidene)-2-mercaptothiazol-4(5H)-one (CAS 1784763-10-5), molecular formula C10H6ClNOS2 and molecular weight 255.74 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (E)-5-(3-Chlorobenzylidene)-2-mercaptothiazol-4(5H)-one (C10H6ClNOS2) 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 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 255.74 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
