Chemical Structure
Description
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2,2'-(Propane-1,2-diylidene)bis(hydrazinecarboximidamide) diacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.26 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.
2,2'-(Propane-1,2-diylidene)bis(hydrazinecarboximidamide) diacetate (CAS 49719-89-3), molecular formula C5H12N8C2H4O2 and molecular weight 244.26 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
