Chemical Structure

H-Thr(tBu)-OMe · HCl CAS 71989-43-0 chemical structure

Description

The occurrence of H-Thr(tBu)-OMe · HCl is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies H-Thr(tBu)-OMe · HCl (CAS 71989-43-0), a certified reference material (molecular formula C9H19NO3HCl, MW 225.71 g/mol) for analytical method development and quality control.

H-Thr(tBu)-OMe · HCl (C9H19NO3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), H-Thr(tBu)-OMe · HCl 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.
