Chemical Structure
Description
5-methylsulfonyl-4,6,7,8-tetrahydro-2H-pyrazolo[4,3-c]azepine (CAS 2230963-25-2) is a high-purity analytical reference standard with the molecular formula C8H17N3O2S and a molecular weight of 219.30 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 5-methylsulfonyl-4,6,7,8-tetrahydro-2H-pyrazolo[4,3-c]azepine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 219.30 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.
