Chemical Structure
Description
The occurrence of 4-Methyl-5-(1-methyl-1H-pyrazol-5-yl)-2-phenyl-1,3-thiazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methyl-5-(1-methyl-1H-pyrazol-5-yl)-2-phenyl-1,3-thiazole (CAS 477709-38-9), molecular formula C14H13N3S and molecular weight 255.34 g/mol, is a CATO reference standard with documented purity and traceability.
4-Methyl-5-(1-methyl-1H-pyrazol-5-yl)-2-phenyl-1,3-thiazole (C14H13N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
