Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 490.04 g/mol gives tert-butyl Nt-trityl-L-histidinate hydrochloride(1:x) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies tert-butyl Nt-trityl-L-histidinate hydrochloride(1:x) (CAS 218938-68-2), a certified reference material (molecular formula C29H31N3O2HCl, MW 490.04 g/mol) for analytical method development and quality control.
Structurally, tert-butyl Nt-trityl-L-histidinate hydrochloride(1:x) (C29H31N3O2HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 490.04 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
