Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-methyl-4-propylthiophene-2-carboxylic acid.
CATO supplies 5-methyl-4-propylthiophene-2-carboxylic acid (CAS 790263-47-7), a certified reference material (molecular formula C9H16O2S, MW 188.29 g/mol) for analytical method development and quality control.
5-methyl-4-propylthiophene-2-carboxylic acid (C9H16O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
