Description
CATO manufactures Naphtho[2,1-d][1,3]oxazol-2-amine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Naphtho[2,1-d][1,3]oxazol-2-amine hydrochloride (CAS 1820734-64-2) is a high-purity analytical reference standard with the molecular formula C11H8N2OHCl and a molecular weight of 220.66 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Naphtho[2,1-d][1,3]oxazol-2-amine hydrochloride is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 220.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
