Chemical Structure

Promurit CAS 5836-73-7 chemical structure

Description

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.

CATO supplies Promurit (CAS 5836-73-7), a certified reference material (molecular formula C7H6Cl2N4S, MW 249.12 g/mol) for analytical method development and quality control.

Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system, Promurit is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.12 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).

As a certified reference material (CRM), Promurit 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.
