Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 125.19 g/mol gives 4-Methyl-5-vinylthiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Methyl-5-vinylthiazole (CAS 1759-28-0) is a high-purity analytical reference standard with the molecular formula C6H7NS and a molecular weight of 125.19 g/mol.
The molecular framework of 4-Methyl-5-vinylthiazole (C6H7NS) is characterized by a nitrile group, sulfur-containing functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
