Chemical Structure
Description
The occurrence of 5-Amino-2,4-dimethylthiazole is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Amino-2,4-dimethylthiazole (CAS 856568-04-2) is a high-purity analytical reference standard with the molecular formula C5H8N2S and a molecular weight of 128.20 g/mol.
Based on its molecular formula C5H8N2S, 5-Amino-2,4-dimethylthiazole contains a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 128.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
