Chemical Structure

5-Bromo-1-trityl-1H-indazole-3-carbaldehyde CAS 2166086-44-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-1-trityl-1H-indazole-3-carbaldehyde.

CATO supplies 5-Bromo-1-trityl-1H-indazole-3-carbaldehyde (CAS 2166086-44-6), a certified reference material (molecular formula C27H19BrN2O, MW 467.36 g/mol) for analytical method development and quality control.

5-Bromo-1-trityl-1H-indazole-3-carbaldehyde (C27H19BrN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
