The occurrence of 2-Butenedioic acid (2Z)-, polymer with 2,2,4-trimethyl-1,3-pentanediol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Butenedioic acid (2Z)-, polymer with 2,2,4-trimethyl-1,3-pentanediol (CAS 26602-21-1), molecular formula C8H18O2C4H4O4 and molecular weight 262.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Butenedioic acid (2Z)-, polymer with 2,2,4-trimethyl-1,3-pentanediol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
