Chemical Structure

tert-Butyl benzyl(4-oxocyclohexyl)carbamate CAS 188562-91-6 chemical structure

Description

The occurrence of tert-Butyl benzyl(4-oxocyclohexyl)carbamate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

tert-Butyl benzyl(4-oxocyclohexyl)carbamate (CAS 188562-91-6) is a high-purity analytical reference standard with the molecular formula C18H25NO3 and a molecular weight of 303.40 g/mol.

tert-Butyl benzyl(4-oxocyclohexyl)carbamate (C18H25NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

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), tert-Butyl benzyl(4-oxocyclohexyl)carbamate 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.
