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 2-methyl-2-sulfopropanoate.
Methyl 2-methyl-2-sulfopropanoate (CAS 146140-34-3) is a high-purity analytical reference standard with the molecular formula C5H9FO4S and a molecular weight of 184.19 g/mol.
The molecular framework of Methyl 2-methyl-2-sulfopropanoate (C5H9FO4S) is characterized by a carbohydrate-derived structure, a sulfone group, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
