Chemical Structure
Description
The occurrence of (E)-2-(2,2-Dimethylhydrazono)acetaldehyde is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-2-(2,2-Dimethylhydrazono)acetaldehyde (CAS 133643-19-3), molecular formula C4H8N2O and molecular weight 100.12 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-2-(2,2-Dimethylhydrazono)acetaldehyde (C4H8N2O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 100.12 g/mol, it falls into the low-molecular-weight range. 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.
