Chemical Structure
Description
Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 3-Methylpyrrolo[2,1-b]thiazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.20 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).
3-Methylpyrrolo[2,1-b]thiazole (CAS 327970-21-8), molecular formula C7H7NS and molecular weight 137.20 g/mol, is a CATO reference standard with documented purity and traceability.
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.
