Chemical Structure
Description
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.
(5-Chloro-2-nitrophenyl)(methyl)sulfane (CAS 70019-41-9), molecular formula C7H6ClNO2S and molecular weight 203.65 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, (5-Chloro-2-nitrophenyl)(methyl)sulfane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.65 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.
As a certified reference material (CRM), (5-Chloro-2-nitrophenyl)(methyl)sulfane 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.
