1-(3,5-Dimethyl-4-(pyrrolidin-1-ylsulfonyl)-1H-pyrazol-1-yl)ethan-1-one CAS 1019105-76-0

Description

The occurrence of 1-(3,5-Dimethyl-4-(pyrrolidin-1-ylsulfonyl)-1H-pyrazol-1-yl)ethan-1-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(3,5-Dimethyl-4-(pyrrolidin-1-ylsulfonyl)-1H-pyrazol-1-yl)ethan-1-one (CAS 1019105-76-0), molecular formula C11H17N3O3S and molecular weight 271.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-(3,5-Dimethyl-4-(pyrrolidin-1-ylsulfonyl)-1H-pyrazol-1-yl)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.34 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.
