Description
As a certified reference material (CRM), 2,2'-(Chloromethylene)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) 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.
2,2'-(Chloromethylene)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) (CAS 2831415-88-2), molecular formula C13H25B2ClO4 and molecular weight 302.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,2'-(Chloromethylene)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) (C13H25B2ClO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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 302.41 g/mol, it falls into the moderately-high-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.
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.
