4-cyclopropyl-2-methylthiazole CAS 128312-58-3 chemical structure

Description

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

CATO supplies 4-cyclopropyl-2-methylthiazole (CAS 128312-58-3), a certified reference material (molecular formula C7H9NS, MW 139.22 g/mol) for analytical method development and quality control.

4-cyclopropyl-2-methylthiazole (C7H9NS) contains a nitrile group, sulfur-containing functionality, an aromatic ring system. Its physicochemical properties are representative of its class; 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.

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.
