Chemical Structure
Description
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 supplies (1S,2R,4S,5R)-5-((Benzyloxy)methyl)-4-(tert-butoxy)bicyclo[3.1.0]hexan-2-ol (CAS 169191-19-9), a certified reference material (molecular formula C18H26O3, MW 290.40 g/mol) for analytical method development and quality control.
Structurally, (1S,2R,4S,5R)-5-((Benzyloxy)methyl)-4-(tert-butoxy)bicyclo[3.1.0]hexan-2-ol (C18H26O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 290.40 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
