6-(1-(3-Chlorophenyl)-1H-pyrazol-5-yl)-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidin-5-one CAS 955976-49-5

Description

Compared with other compounds in its class, the molecular weight of 330.79 g/mol gives 6-(1-(3-Chlorophenyl)-1H-pyrazol-5-yl)-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidin-5-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-(1-(3-Chlorophenyl)-1H-pyrazol-5-yl)-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidin-5-one (CAS 955976-49-5), molecular formula C15H11ClN4OS and molecular weight 330.79 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-(1-(3-Chlorophenyl)-1H-pyrazol-5-yl)-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidin-5-one (C15H11ClN4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
