Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-((4-Bromophenyl)diazenyl)-2-hydroxybenzaldehyde.
5-((4-Bromophenyl)diazenyl)-2-hydroxybenzaldehyde (CAS 123692-94-4), molecular formula C13H9BrN2O2 and molecular weight 305.13 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-((4-Bromophenyl)diazenyl)-2-hydroxybenzaldehyde (C13H9BrN2O2) 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 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 305.13 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
