Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,3-Dimethyl-1-{3-[3-(thiophen-2-yl)pyrazolo[1,5-a]pyrimidin-7-yl]phenyl}azetidin-2-one.
3,3-Dimethyl-1-{3-[3-(thiophen-2-yl)pyrazolo[1,5-a]pyrimidin-7-yl]phenyl}azetidin-2-one (CAS 861210-48-2), molecular formula C21H18N4OS and molecular weight 374.46 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,3-Dimethyl-1-{3-[3-(thiophen-2-yl)pyrazolo[1,5-a]pyrimidin-7-yl]phenyl}azetidin-2-one (C21H18N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 374.46 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 3,3-Dimethyl-1-{3-[3-(thiophen-2-yl)pyrazolo[1,5-a]pyrimidin-7-yl]phenyl}azetidin-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
