Description
CATO supplies 608-37-7 2-Butenedioic acid, 2,3-dibromo-, (Z)- (9CI) 2-Butenedioic acid, 2,3-dibromo-, (2Z)- 2,3-Dibromomaleic acid 2-Butenedioic acid, 2,3-dibromo-, (Z)- Dibromomaleic acid EINECS 210-162-6 Maleic acid, dibromo- NSC 263482 (CAS 608-37-7), a certified reference material (molecular formula C4H2Br2O4, MW 273.86 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, bromine substitution, 608-37-7 2-Butenedioic acid, 2,3-dibromo-, (Z)- (9CI) 2-Butenedioic acid, 2,3-dibromo-, (2Z)- 2,3-Dibromomaleic acid 2-Butenedioic acid, 2,3-dibromo-, (Z)- Dibromomaleic acid EINECS 210-162-6 Maleic acid, dibromo- NSC 263482 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
