Chemical Structure

Tert-butyl (5aR,8aR)-3-(2-fluorophenyl)-5a,6,8,8a-tetrahydro-4H,7H-pyrrolo[3,4-b][1,2,3]triazolo[1,5-d][1,4]oxazine-7-carboxylate CAS 1632258-65-1 chemical structure

Description

The occurrence of Tert-butyl (5aR,8aR)-3-(2-fluorophenyl)-5a,6,8,8a-tetrahydro-4H,7H-pyrrolo[3,4-b][1,2,3]triazolo[1,5-d][1,4]oxazine-7-carboxylate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tert-butyl (5aR,8aR)-3-(2-fluorophenyl)-5a,6,8,8a-tetrahydro-4H,7H-pyrrolo[3,4-b][1,2,3]triazolo[1,5-d][1,4]oxazine-7-carboxylate (CAS 1632258-65-1) is a high-purity analytical reference standard with the molecular formula C18H21FN4O3 and a molecular weight of 360.38 g/mol.

Tert-butyl (5aR,8aR)-3-(2-fluorophenyl)-5a,6,8,8a-tetrahydro-4H,7H-pyrrolo[3,4-b][1,2,3]triazolo[1,5-d][1,4]oxazine-7-carboxylate (C18H21FN4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. 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.

As a certified reference material (CRM), Tert-butyl (5aR,8aR)-3-(2-fluorophenyl)-5a,6,8,8a-tetrahydro-4H,7H-pyrrolo[3,4-b][1,2,3]triazolo[1,5-d][1,4]oxazine-7-carboxylate 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.
