1H-1,2,3-benzotriazol-1-ylmethanol 1H-1,2,3-benzotriazole-1-methanol 28539-02-8 InChI=1/C7H7N3O/c11-5-10-7-4-2-1-3-6(7)8-9-10/h1-4,11H,5H CAS 28539-02-8

Description

Structurally, 1H-1,2,3-benzotriazol-1-ylmethanol 1H-1,2,3-benzotriazole-1-methanol 28539-02-8 InChI=1/C7H7N3O/c11-5-10-7-4-2-1-3-6(7)8-9-10/h1-4,11H,5H (C7H15N3O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 157.21 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

1H-1,2,3-benzotriazol-1-ylmethanol 1H-1,2,3-benzotriazole-1-methanol 28539-02-8 InChI=1/C7H7N3O/c11-5-10-7-4-2-1-3-6(7)8-9-10/h1-4,11H,5H (CAS 28539-02-8), molecular formula C7H15N3O and molecular weight 157.21 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
