2-Phenyl-1H-1,3-benzodiazole-5-sulfonyl chloride CAS 27503-82-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Phenyl-1H-1,3-benzodiazole-5-sulfonyl chloride.

2-Phenyl-1H-1,3-benzodiazole-5-sulfonyl chloride (CAS 27503-82-8) is a high-purity analytical reference standard with the molecular formula C13H9ClN2O2S and a molecular weight of 292.74 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Phenyl-1H-1,3-benzodiazole-5-sulfonyl chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
