Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 123.58 g/mol gives Isopropyl formimidate hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Isopropyl formimidate hydrochloride (CAS 16694-44-3), molecular formula C4H9NOHCl and molecular weight 123.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Isopropyl formimidate hydrochloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 123.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
