Toluene-4-sulfonic acid 4-tert-butoxycarbonylamino-cyclohexyl ester CAS 1017241-31-4

Description

The occurrence of Toluene-4-sulfonic acid 4-tert-butoxycarbonylamino-cyclohexyl ester is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Toluene-4-sulfonic acid 4-tert-butoxycarbonylamino-cyclohexyl ester (CAS 1017241-31-4), molecular formula C18H27NO5S and molecular weight 369.48 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Toluene-4-sulfonic acid 4-tert-butoxycarbonylamino-cyclohexyl ester (C18H27NO5S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
