Chemical Structure

1-Mercapto-5-carbomethoxy-pentane CAS 20756-86-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 162.25 g/mol gives 1-Mercapto-5-carbomethoxy-pentane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Mercapto-5-carbomethoxy-pentane (CAS 20756-86-9) is a high-purity analytical reference standard with the molecular formula C7H14O2S and a molecular weight of 162.25 g/mol.

The molecular framework of 1-Mercapto-5-carbomethoxy-pentane (C7H14O2S) 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.

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.
