Sb Standard Solution CAS 7440-36-0 chemical structure

Description

CATO supplies Sb Standard Solution (CAS 7440-36-0), a certified reference material (molecular formula Sb, MW 121.76 g/mol) for analytical method development and quality control.

Owing to an inorganic composition, Sb Standard Solution is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 121.76 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.
