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.

V23UK0CYXL 71418-44-5 Monobromobimane 1H,7H-Pyrazolo(1,2-a)pyrazole-1,7-dione, 3-(bromomethyl)-2,5,6-trimethyl- Bromobimane MBBR Thiolyte MB 3-(Bromomethyl)-2,5,6-trimethyl-1H,7H-pyrazolo(1,2-a)pyrazole-1,7-dione UNII-V23UK0CYXL (CAS 71418-44-5) is a high-purity analytical reference standard with the molecular formula C10H11BrN2O2 and a molecular weight of 271.11 g/mol.

Structurally, V23UK0CYXL 71418-44-5 Monobromobimane 1H,7H-Pyrazolo(1,2-a)pyrazole-1,7-dione, 3-(bromomethyl)-2,5,6-trimethyl- Bromobimane MBBR Thiolyte MB 3-(Bromomethyl)-2,5,6-trimethyl-1H,7H-pyrazolo(1,2-a)pyrazole-1,7-dione UNII-V23UK0CYXL (C10H11BrN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 271.11 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), V23UK0CYXL 71418-44-5 Monobromobimane 1H,7H-Pyrazolo(1,2-a)pyrazole-1,7-dione, 3-(bromomethyl)-2,5,6-trimethyl- Bromobimane MBBR Thiolyte MB 3-(Bromomethyl)-2,5,6-trimethyl-1H,7H-pyrazolo(1,2-a)pyrazole-1,7-dione UNII-V23UK0CYXL 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.
