Chemical Structure

6-[[(Benzyloxy)carbonyl]amino]hexanoic acid tert-butyl ester CAS 158141-67-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-[[(Benzyloxy)carbonyl]amino]hexanoic acid tert-butyl ester.

6-[[(Benzyloxy)carbonyl]amino]hexanoic acid tert-butyl ester (CAS 158141-67-4), molecular formula C18H27NO4 and molecular weight 321.41 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 6-[[(Benzyloxy)carbonyl]amino]hexanoic acid tert-butyl ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
