Chemical Structure

2,6-difluoropyrazine CAS 33873-09-5 chemical structure

Description

2,6-difluoropyrazine (CAS 33873-09-5) is a high-purity analytical reference standard with the molecular formula C4H8F2N2 and a molecular weight of 122.12 g/mol.

Structurally, 2,6-difluoropyrazine (C4H8F2N2) contains fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 122.12 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2,6-difluoropyrazine 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.
