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 cis-1,3-Cyclobutanediol, 1-methyl-, 3-(4-methylbenzenesulfonate).
cis-1,3-Cyclobutanediol, 1-methyl-, 3-(4-methylbenzenesulfonate) (CAS 2411494-74-9) is a high-purity analytical reference standard with the molecular formula C12H16O4S and a molecular weight of 256.32 g/mol.
cis-1,3-Cyclobutanediol, 1-methyl-, 3-(4-methylbenzenesulfonate) (C12H16O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
