tert-Butyl (3aR,4S,7aR)-4-hydroxy-4-(m-tolylethynyl)octahydro-1H-indole-1-carboxylate CAS 543910-55-0 chemical structure

Description

The occurrence of tert-Butyl (3aR,4S,7aR)-4-hydroxy-4-(m-tolylethynyl)octahydro-1H-indole-1-carboxylate 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 (3aR,4S,7aR)-4-hydroxy-4-(m-tolylethynyl)octahydro-1H-indole-1-carboxylate (CAS 543910-55-0), molecular formula C22H29NO3 and molecular weight 355.47 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, tert-Butyl (3aR,4S,7aR)-4-hydroxy-4-(m-tolylethynyl)octahydro-1H-indole-1-carboxylate (C22H29NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 355.47 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 (3aR,4S,7aR)-4-hydroxy-4-(m-tolylethynyl)octahydro-1H-indole-1-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.
