2-(bromomethyl)spiro[4,6-dihydropyrrolo[1,2-b]pyrazole-5,1'-cyclopropane] CAS 2853613-49-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(bromomethyl)spiro[4,6-dihydropyrrolo[1,2-b]pyrazole-5,1'-cyclopropane].

2-(bromomethyl)spiro[4,6-dihydropyrrolo[1,2-b]pyrazole-5,1'-cyclopropane] (CAS 2853613-49-5), molecular formula C9H11BrN2 and molecular weight 227.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 2-(bromomethyl)spiro[4,6-dihydropyrrolo[1,2-b]pyrazole-5,1'-cyclopropane] is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 227.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
