Chemical Structure
Description
CATO supplies 3-Methylpentane-1-thiol (CAS 1633-88-1), a certified reference material (molecular formula C6H14S, MW 118.24 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, 3-Methylpentane-1-thiol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 118.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
