Chemical Structure

Urea CAS 57-13-6 chemical structure

Description

Urea (CAS 57-13-6) is a high-purity analytical reference standard with the molecular formula CH4N2O and a molecular weight of 60.06 g/mol.

Owing to a hydroxyl group, Urea is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 60.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Urea 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.
