Chemical Structure

(S)-Butane-1,2-diol CAS 73522-17-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 90.12 g/mol gives (S)-Butane-1,2-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(S)-Butane-1,2-diol (CAS 73522-17-5), molecular formula C4H10O2 and molecular weight 90.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-Butane-1,2-diol (C4H10O2) is characterized by 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.

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.
