Description
306936-19-6 5-(tert-Butyl)-1,2-[(2-hydroxyethyl)thio]ethyl-2-methyl-1H-pyrrole-3-carboxylic acid 5-tert-butyl-1-(2-(2-hydroxyethylthio)ethyl)-2-methyl-1H-pyrrole-3-carboxylic acid (CAS 306936-19-6), molecular formula C14H25NO3S and molecular weight 287.42 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 306936-19-6 5-(tert-Butyl)-1,2-[(2-hydroxyethyl)thio]ethyl-2-methyl-1H-pyrrole-3-carboxylic acid 5-tert-butyl-1-(2-(2-hydroxyethylthio)ethyl)-2-methyl-1H-pyrrole-3-carboxylic acid (C14H25NO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 287.42 g/mol, it falls into the medium-molecular-weight range. 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.
