Chemical Structure
Description
Pyridine, 5-ethenyl-2-methyl-, polymer with 1,3-butadiene (CAS 25085-55-6), molecular formula C8H9NC4H6 and molecular weight 173.26 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Pyridine, 5-ethenyl-2-methyl-, polymer with 1,3-butadiene (C8H9NC4H6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 173.26 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Pyridine, 5-ethenyl-2-methyl-, polymer with 1,3-butadiene 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.
