Chemical Structure

6-Chloro-2-pyrazinecarbaldehyde CAS 874114-34-8 chemical structure

Description

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-2-pyrazinecarbaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

6-Chloro-2-pyrazinecarbaldehyde (CAS 874114-34-8) is a high-purity analytical reference standard with the molecular formula C5H3ClN2O and a molecular weight of 142.54 g/mol.

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), 6-Chloro-2-pyrazinecarbaldehyde 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.
