Chemical Structure

2-Hydroxybut-3-enenitrile CAS 5809-59-6 chemical structure

Description

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

CATO supplies 2-Hydroxybut-3-enenitrile (CAS 5809-59-6), a certified reference material (molecular formula C4H5NO, MW 83.09 g/mol) for analytical method development and quality control.

Structurally, 2-Hydroxybut-3-enenitrile (C4H5NO) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 83.09 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 2-Hydroxybut-3-enenitrile 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.
