Chemical Structure
Description
The occurrence of Naphtho[1,2-<I>c</I>:5,6-<I>c</I>′]bis[1,2,5]thiadiazole-5,10-diboronic acid bis(pinacol) ester is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Naphtho[1,2-<I>c</I>:5,6-<I>c</I>′]bis[1,2,5]thiadiazole-5,10-diboronic acid bis(pinacol) ester (CAS 1467776-41-5), molecular formula C22H26B2N4O4S2 and molecular weight 496.22 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H26B2N4O4S2, Naphtho[1,2-<I>c</I>:5,6-<I>c</I>′]bis[1,2,5]thiadiazole-5,10-diboronic acid bis(pinacol) ester contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 496.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
