(<I>S</I>)-3-butene-1,2-diol-1-(p-toluenesulfonate) CAS 133095-74-6 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 (<I>S</I>)-3-butene-1,2-diol-1-(p-toluenesulfonate).

(<I>S</I>)-3-butene-1,2-diol-1-(p-toluenesulfonate) (CAS 133095-74-6), molecular formula C11H20O4S and molecular weight 248.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (<I>S</I>)-3-butene-1,2-diol-1-(p-toluenesulfonate) (C11H20O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 248.34 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
