Chemical Structure

Sulfuric Acid Monoallyl Ester CAS 21706-75-2 chemical structure

Description

The occurrence of Sulfuric Acid Monoallyl Ester is closely related to a sulfone group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sulfuric Acid Monoallyl Ester (CAS 21706-75-2) is a high-purity analytical reference standard with the molecular formula C3H5O4S and a molecular weight of 137.13 g/mol.

Owing to a sulfone group, a carboxylic acid group, an ether linkage, Sulfuric Acid Monoallyl Ester is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
