Chemical Structure

(1Z,2E)-N-Hydroxy-2-(hydroxyimino)propanimidamide CAS 4937-85-3 chemical structure

Description

The molecular framework of (1Z,2E)-N-Hydroxy-2-(hydroxyimino)propanimidamide (C3H7N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

(1Z,2E)-N-Hydroxy-2-(hydroxyimino)propanimidamide (CAS 4937-85-3) is a high-purity analytical reference standard with the molecular formula C3H7N3O2 and a molecular weight of 117.11 g/mol.

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.
