Chemical Structure

1-Mercaptopropan-2-one oxime CAS 175137-00-5 chemical structure

Description

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.

CATO supplies 1-Mercaptopropan-2-one oxime (CAS 175137-00-5), a certified reference material (molecular formula C3H7NOS, MW 105.16 g/mol) for analytical method development and quality control.

Structurally, 1-Mercaptopropan-2-one oxime (C3H7NOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 105.16 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
