Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 154.01 g/mol gives 2-Aminoacetamidine Dihydrobromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Aminoacetamidine Dihydrobromide (CAS 69816-37-1), molecular formula HBrC2H7N3 and molecular weight 154.01 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, 2-Aminoacetamidine Dihydrobromide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.01 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.
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.
