(5E)-2-Mercapto-5-(3-methylbenzylidene)-1,3-thiazol-4(5H)-one 127378-26-1 3439AD C11H9NOS2 CAS 127378-26-1

Description

The occurrence of (5E)-2-Mercapto-5-(3-methylbenzylidene)-1,3-thiazol-4(5H)-one 127378-26-1 3439AD C11H9NOS2 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(5E)-2-Mercapto-5-(3-methylbenzylidene)-1,3-thiazol-4(5H)-one 127378-26-1 3439AD C11H9NOS2 (CAS 127378-26-1), molecular formula C11H9NOS2 and molecular weight 235.33 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (5E)-2-Mercapto-5-(3-methylbenzylidene)-1,3-thiazol-4(5H)-one 127378-26-1 3439AD C11H9NOS2 (C11H9NOS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 235.33 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
