Chemical Structure

(Z)-Ethyl 2-amino-2-(hydroxyimino)acetate CAS 144167-29-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Z)-Ethyl 2-amino-2-(hydroxyimino)acetate.

(Z)-Ethyl 2-amino-2-(hydroxyimino)acetate (CAS 144167-29-3) is a high-purity analytical reference standard with the molecular formula C4H8N2O3 and a molecular weight of 132.12 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (Z)-Ethyl 2-amino-2-(hydroxyimino)acetate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.12 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), (Z)-Ethyl 2-amino-2-(hydroxyimino)acetate 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.
