Chemical Structure

H-His(Trt)-OH CAS 35146-32-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies H-His(Trt)-OH (CAS 35146-32-8), a certified reference material (molecular formula C25H23N3O2, MW 397.47 g/mol) for analytical method development and quality control.

Structurally, H-His(Trt)-OH (C25H23N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 397.47 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
