Chemical Structure
Description
The occurrence of 3-Methoxybenzene-1,2-diamine sulfate 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.
3-Methoxybenzene-1,2-diamine sulfate (CAS 659729-60-9), molecular formula C7H10N2OH2O4S and molecular weight 236.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Methoxybenzene-1,2-diamine sulfate (C7H10N2OH2O4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Methoxybenzene-1,2-diamine sulfate 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.
