Chemical Structure

(3,4-Diaminophenyl)-(2-thienyl)methanone, Dihydrochloride Discontinued. See D416601 CAS 355115-86-5 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 (3,4-Diaminophenyl)-(2-thienyl)methanone, Dihydrochloride Discontinued. See D416601.

CATO supplies (3,4-Diaminophenyl)-(2-thienyl)methanone, Dihydrochloride Discontinued. See D416601 (CAS 355115-86-5), a certified reference material (molecular formula C11H10N2OSHCl, MW 254.73 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, (3,4-Diaminophenyl)-(2-thienyl)methanone, Dihydrochloride Discontinued. See D416601 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 254.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

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.
