MLS 1547 CAS 315698-36-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 354.83 g/mol gives MLS 1547 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

MLS 1547 (CAS 315698-36-3), molecular formula C19H19ClN4O and molecular weight 354.83 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C19H19ClN4O, MLS 1547 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 354.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), MLS 1547 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.
