Chemical Structure

Acetyl(methyl)carbamic chloride CAS 21777-48-0 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.

Acetyl(methyl)carbamic chloride (CAS 21777-48-0) is a high-purity analytical reference standard with the molecular formula C4H6ClNO2 and a molecular weight of 135.55 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Acetyl(methyl)carbamic chloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 135.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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