Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Butanedioic acid, 2-methylene-, polymer with 1,1-dichloroethene and 2-propenenitrile (CAS 25053-68-3), molecular formula C5H6O4C2H2Cl2C3H3N and molecular weight 280.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Butanedioic acid, 2-methylene-, polymer with 1,1-dichloroethene and 2-propenenitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Butanedioic acid, 2-methylene-, polymer with 1,1-dichloroethene and 2-propenenitrile 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.
