2-Chloro-1-[2,5-dimethyl-1-(5-methyl-1,2-oxazol-3-yl)-1h-pyrrol-3-yl]ethan-1-one CAS 747411-07-0

Description

Compared with other compounds in its class, the molecular weight of 252.70 g/mol gives 2-Chloro-1-[2,5-dimethyl-1-(5-methyl-1,2-oxazol-3-yl)-1h-pyrrol-3-yl]ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-1-[2,5-dimethyl-1-(5-methyl-1,2-oxazol-3-yl)-1h-pyrrol-3-yl]ethan-1-one (CAS 747411-07-0), molecular formula C12H13ClN2O2 and molecular weight 252.70 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-1-[2,5-dimethyl-1-(5-methyl-1,2-oxazol-3-yl)-1h-pyrrol-3-yl]ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.70 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.
