(S)-1-(1-hydroxypropan-2-yl)-3-phenylurea CAS 618856-85-2

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.

(S)-1-(1-hydroxypropan-2-yl)-3-phenylurea (CAS 618856-85-2), molecular formula C10H14N2O2 and molecular weight 194.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (S)-1-(1-hydroxypropan-2-yl)-3-phenylurea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.23 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), (S)-1-(1-hydroxypropan-2-yl)-3-phenylurea 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.
