Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-Methyl-5-(4-methyl-5-(prop-2-yn-1-ylthio)-4H-1,2,4-triazol-3-yl)-2-phenylthiazole (CAS 338760-00-2), molecular formula C16H14N4S2 and molecular weight 326.44 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Methyl-5-(4-methyl-5-(prop-2-yn-1-ylthio)-4H-1,2,4-triazol-3-yl)-2-phenylthiazole (C16H14N4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 326.44 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.

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.
