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 methyl 3-(acetylsulfanyl)-2-methylbutanoate.
methyl 3-(acetylsulfanyl)-2-methylbutanoate (CAS 1221397-61-0), molecular formula C8H14O3S and molecular weight 190.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of methyl 3-(acetylsulfanyl)-2-methylbutanoate (C8H14O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
