Description
As a certified reference material (CRM), 4-{2-[(naphthalen-1-yl)amino]-1,3-thiazol-4-yl}benzene-1,2-diol hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-{2-[(naphthalen-1-yl)amino]-1,3-thiazol-4-yl}benzene-1,2-diol hydrochloride (CAS 1135298-34-8) is a high-purity analytical reference standard with the molecular formula C19H15N2O2SCl and a molecular weight of 370.85 g/mol.
The molecular framework of 4-{2-[(naphthalen-1-yl)amino]-1,3-thiazol-4-yl}benzene-1,2-diol hydrochloride (C19H15N2O2SCl) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
