Chemical Structure
Description
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.
CATO supplies 3-Methylthiophene-2-carboximidamide (CAS 148580-57-8), a certified reference material (molecular formula C6H8N2S, MW 140.21 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 3-Methylthiophene-2-carboximidamide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
