Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5'H-Spiro[cyclopropane-1,8'-imidazo[1,5-a]pyridine] is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.19 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.
CATO supplies 5'H-Spiro[cyclopropane-1,8'-imidazo[1,5-a]pyridine] (CAS 345633-67-2), a certified reference material (molecular formula C9H10N2, MW 146.19 g/mol) for analytical method development and quality control.
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.
