N-Chloroacetyl-DL-alanine CAS 1190-32-5

Description

Compared with other compounds in its class, the molecular weight of 165.57 g/mol gives N-Chloroacetyl-DL-alanine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-Chloroacetyl-DL-alanine (CAS 1190-32-5) is a high-purity analytical reference standard with the molecular formula C5H8ClNO3 and a molecular weight of 165.57 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, N-Chloroacetyl-DL-alanine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 165.57 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.

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.

As a certified reference material (CRM), N-Chloroacetyl-DL-alanine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
