Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-benzothiazol-6-ol 2-Amino-6-hydroxybenzothiazole 2-Amino-6-benzothiazolol 6-Hydroxy-2-aminobenzothiazole 6-Hydroxybenzothiazol-2-amine 2-Aminobenzo[d]thiazol-6-ol 2-Amino-1,3-benzothiazol-6-ol 26278-79-5.

2-Amino-benzothiazol-6-ol 2-Amino-6-hydroxybenzothiazole 2-Amino-6-benzothiazolol 6-Hydroxy-2-aminobenzothiazole 6-Hydroxybenzothiazol-2-amine 2-Aminobenzo[d]thiazol-6-ol 2-Amino-1,3-benzothiazol-6-ol 26278-79-5 (CAS 26278-79-5), molecular formula C7H14N2OS and molecular weight 174.26 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H14N2OS, 2-Amino-benzothiazol-6-ol 2-Amino-6-hydroxybenzothiazole 2-Amino-6-benzothiazolol 6-Hydroxy-2-aminobenzothiazole 6-Hydroxybenzothiazol-2-amine 2-Aminobenzo[d]thiazol-6-ol 2-Amino-1,3-benzothiazol-6-ol 26278-79-5 contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 174.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
