Chemical Structure

(S)-4-(tert-Butoxycarbonyl)-3-methylmorpholine-3-carboxylic acid CAS 1638744-49-6 chemical structure

Description

The occurrence of (S)-4-(tert-Butoxycarbonyl)-3-methylmorpholine-3-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-4-(tert-Butoxycarbonyl)-3-methylmorpholine-3-carboxylic acid (CAS 1638744-49-6) is a high-purity analytical reference standard with the molecular formula C11H19NO5 and a molecular weight of 245.27 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (S)-4-(tert-Butoxycarbonyl)-3-methylmorpholine-3-carboxylic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 245.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), (S)-4-(tert-Butoxycarbonyl)-3-methylmorpholine-3-carboxylic acid 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.
