Chemical Structure

4-Amino-3-methylbenzene-1,2-diol CAS 93940-92-2 chemical structure

Description

The occurrence of 4-Amino-3-methylbenzene-1,2-diol is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Amino-3-methylbenzene-1,2-diol (CAS 93940-92-2) is a high-purity analytical reference standard with the molecular formula C7H9NO2 and a molecular weight of 139.15 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-Amino-3-methylbenzene-1,2-diol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 4-Amino-3-methylbenzene-1,2-diol 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.
