(5R,7R)-4-(4-Boc-1-piperazinyl)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol CAS 1001180-45-5 chemical structure

Description

(5R,7R)-4-(4-Boc-1-piperazinyl)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol (C28H37ClFN5O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

(5R,7R)-4-(4-Boc-1-piperazinyl)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol (CAS 1001180-45-5) is a high-purity analytical reference standard with the molecular formula C28H37ClFN5O3 and a molecular weight of 546.08 g/mol.

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.

As a certified reference material (CRM), (5R,7R)-4-(4-Boc-1-piperazinyl)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
