Description

The occurrence of 941-55-9 97F7BLE97S p-Toluenesulfonyl azide Benzenesulfonyl azide, 4-methyl- p-Toluenesulfonyl azide (8CI) Tosyl azide Azido-p-toluenesulfonic acid EINECS 213-381-5 p-Methylphenylsulfonyl azide NSC 138649 p-Toluenesulfonazide p-Toluenesulfonic acid azide p-Tolylsulfonyl azide Tosyl nitride UNII-97F7BLE97S is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

941-55-9 97F7BLE97S p-Toluenesulfonyl azide Benzenesulfonyl azide, 4-methyl- p-Toluenesulfonyl azide (8CI) Tosyl azide Azido-p-toluenesulfonic acid EINECS 213-381-5 p-Methylphenylsulfonyl azide NSC 138649 p-Toluenesulfonazide p-Toluenesulfonic acid azide p-Tolylsulfonyl azide Tosyl nitride UNII-97F7BLE97S (CAS 941-55-9) is a high-purity analytical reference standard with the molecular formula C7H13N3O2S and a molecular weight of 203.26 g/mol.

Structurally, 941-55-9 97F7BLE97S p-Toluenesulfonyl azide Benzenesulfonyl azide, 4-methyl- p-Toluenesulfonyl azide (8CI) Tosyl azide Azido-p-toluenesulfonic acid EINECS 213-381-5 p-Methylphenylsulfonyl azide NSC 138649 p-Toluenesulfonazide p-Toluenesulfonic acid azide p-Tolylsulfonyl azide Tosyl nitride UNII-97F7BLE97S (C7H13N3O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 203.26 g/mol, it falls into the medium-molecular-weight range. 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.
