Chemical Structure

Acetyl-L-alaninoyl chloride CAS 76965-63-4 chemical structure

Description

Acetyl-L-alaninoyl chloride (CAS 76965-63-4), molecular formula C5H8ClNO2 and molecular weight 149.58 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Acetyl-L-alaninoyl chloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.58 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.

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.
